ABSTRACT

Purpose: To evaluate binocular intermediate visual acuity (IVA), depth of focus, and other visual outcomes achieved with a monofocal aspheric intraocular lens (IOL) using pooled data from 2 randomized, double-masked, controlled trials. Patients and Methods: The studies conducted at 32 sites included patients aged ≥22 years with bilateral cataracts, preoperative corneal astigmatism 1.0 D, and lens power 18.0-25.0 D. Patients received bilateral AcrySof IQ IOLs (SN60WF). Primary endpoint data were collected at month 6. Binocular uncorrected and corrected distance visual acuity (UDVA and CDVA) at 4 m, binocular uncorrected and corrected IVA (UIVA and DCIVA) at 66 cm, manifest refraction spherical equivalent (MRSE), and binocular defocus curve at 4 m were assessed under photopic conditions. Validated questionnaires were used to assess spectacle use and quality of vision. Results: Of 233 patients who received SN60WF, 228 had visual acuity data at 6 months. Under photopic conditions, 51% of the eyes had pupils >4 mm, 40% had pupils 3-4 mm, and 9% had pupils <3 mm. Mean ± SD UDVA and CDVA were -0.019 ± 0.110 and -0.088 ± 0.082 logMAR, respectively. Mean ± SD UIVA and DCIVA were 0.125 ± 0.145 and 0.196 ± 0.139 logMAR, respectively. UIVA and DCIVA of 20/32 or better were achieved by 83% (188/228) and 71% (162/228) of patients, respectively. Mean ± SD MRSE was -0.007 ± 0.404 D for the first eye and 0.036 ± 0.371 for the second eye. The defocus curve demonstrated binocular vision of 0.24 logMAR or better from +1.2 to -1.5 D. Spectacle independence for distance and intermediate vision was reported by 86% and 41% of the patients, respectively. Based on questionnaires, 61%, 79%, and 65% of the patients did not experience starbursts, halos, or glare. Conclusion: A monofocal aspheric IOL (SN60WF) assessed in a large, pooled study provided excellent distance vision and clinically functional intermediate vision.

ABSTRACT

Purpose: To evaluate the long-term (>1 yr) outcomes a non-diffractive extended vision intraocular lens (AcrySof IQ Vivity) compared to monofocal control. Setting: This was a multicenter trial that took place in 4 separate private ophthalmology practices throughout the United States. Design: This was a prospective, non-interventional, controlled, multicenter trial. All subjects were enrolled from participants in the Food and Drug Administration (FDA) clinical trial that led to the approval of the AcrySof IQ Vivity. Methods: Binocular uncorrected distance visual acuity (UCDVA), distance corrected visual acuity (DCVA), uncorrected intermediate visual acuity (UIVA) at 66cm, distance corrected intermediate visual acuity (DCIVA) at 66cm, uncorrected near visual acuity (UNVA) at 40cm, and distance corrected near visual acuity (DCNVA) at 40cm were measured. The binocular defocus curve was measured. A 23-question survey on visual performance including questions on spectacle independence, satisfaction, dysphotopsias, and likelihood of recommending their lens to another person was used administered. Results: A total of 64 eyes of 32 subjects were enrolled. Seventeen subjects had bilateral implantation of the AcrySof IQ Vivity lens, and 15 subjects had bilateral implantation of the AcrySof IQ Monofocal (SN60WF). Mean follow up time was 1078 days for the study group compared to 1067 days for the control group (p = 0.92). There were no differences in UCVA or DCVA between the two groups. Compared to control, the AcrySof IQ Vivity group had better mean binocular UIVA (logMAR 0.29 vs 0.18; p = 0.09), DCIVA (logMAR 0.33 vs 0.11; p = 0.003), UNVA (logMAR 0.49 vs 0.30, p = 0.01), and DCNVA (logMAR 0.54 vs 0.29; p = 0.001). Conclusion: The AcrySof IQ Vivity is a novel, non-diffractive extended range of vision intraocular lens that provides long-term, enhanced visual acuity at intermediate and near ranges with high levels of patient satisfaction and minimal dysphotopsias.

ABSTRACT

Purpose: To evaluate dexamethasone intraocular suspension 9% (intraocular DXM) in real-world clinical use to manage inflammation associated with cataract surgery. Setting: Patients who underwent cataract surgery and received intraocular DXM at 22 outpatient eye surgery centers in the US. Design: Retrospective, observational chart review. Methods: Records of all patients who received intraocular DXM from March to December 2019 at participating centers were reviewed. Main Outcome Measures: Outcomes included anterior chamber cell (ACC) grades, anterior chamber flare (ACF) grades, and visual acuity, as well as intraocular pressure (IOP) and adverse events (AEs) at postoperative days (PODs) 1, 8, 14, 30. Descriptive statistics were generated. Results: The study population included 527 patients (641 eyes), with glaucoma history in 66 patients (80 eyes). Among eyes with recorded ACC grades, the percentage with grade 0 increased from 40% at POD 1 to 89.7% at POD 30, with similar results in eyes with glaucoma history. Among eyes with recorded ACF grades, the percentage with grade 0 increased from 78.4% at POD 1 to 97.1% at POD 30. At POD 30, 96.6% eyes with recorded results achieved target acuity. Mean IOP was 18.6 mmHg at POD 1 but declined to ≤15.2 mmHg thereafter. Investigators reported 22 AEs in 20 patients, all reported mild or moderate, the most common: IOP increase (7 events). Conclusion: Patients undergoing cataract surgery and treated with intraocular DXM showed favorable inflammatory and visual outcomes, without unanticipated safety problems, consistent with results of previous controlled clinical trials.

ABSTRACT

Corticosteroids and non-steroidal anti-inflammatory drugs are commonly used prophylactically to control inflammation after ocular surgery. When prescribed as eye drops, as has been longstanding tradition, anti-inflammatory success is out of surgeons' hands, dependent on patient compliance and proper instillation technique. Sustained-release, intraoperatively administered anti-inflammatory drugs are emerging as another option. DEXYCU (dexamethasone intraocular suspension) 9% is the first and only intraocular corticosteroid FDA-approved for postoperative inflammation, whose sustained-release formulation provides a high initial release of drug, followed by a gradual tapering. Administration of the drug directly into the capsular bag following cataract surgery enables reliable placement proximal to target tissues, ensuring surgeon control and visibility of delivery, safety, and efficiency. This technique also minimizes contact with metabolically active tissues such as the corneal endothelium, iris, and ciliary body. In this paper, we review the available literature on dexamethasone intraocular suspension and summarize surgeons' consensus on best practices for intracapsular administration.

ABSTRACT

PURPOSE: To evaluate the effectiveness and safety of the DFT015 intraocular lens (IOL) (AcrySof IQ Vivity Extended Vision) compared with an aspheric monofocal control IOL (AcrySof IQ model SN60WF). SETTING: 11 investigation sites in the U.S. DESIGN: Prospective randomized controlled clinical study. METHODS: Patients aged 22 years or older with bilateral cataracts were randomized to receive bilateral implantation of DFT015 or SN60WF. The 4 coprimary effectiveness outcomes (6 months postoperatively) were monocular photopic distance-corrected intermediate visual acuity (DCIVA), monocular photopic corrected distance visual acuity (CDVA), monocular depth of focus (DoF), and the percentage of patients achieving a DCIVA of 0.2 logMAR or better. The mean monocular photopic distance-corrected near visual acuity (DCNVA) was a secondary effectiveness outcome. Safety and patient-reported visual disturbances were evaluated through questionnaires. RESULTS: 218 patients (435 eyes) completed the study. Compared with SN60WF, DFT015 demonstrated superior mean monocular photopic DCIVA ( P &lt; .001), noninferior mean monocular photopic CDVA, and superior mean monocular photopic DCNVA ( P &lt; .001) and provided an extended monocular DoF (increase of 0.54 diopters at 0.2 logMAR). With DFT015, 78 first eyes (72.9%) achieved a DCIVA of 0.2 logMAR or better at 6 months. Incidences of ocular serious adverse events and patient-reported most bothersome visual disturbances were low and consistent between groups. CONCLUSIONS: DFT015 is safe and effective for the visual correction of aphakia, exceeding American National Standards Institute criteria for an extended depth-of-focus IOL by providing superior DCIVA and DCNVA, with comparable CDVA and visual disturbances to the SN60WF monofocal IOL.

ABSTRACT

This position article on reducing topical drug waste with ophthalmic surgery was written by the Ophthalmic Instrument Cleaning and Sterilization Task Force, comprising representatives of the ASCRS, American Academy of Ophthalmology, American Glaucoma Society, and Outpatient Ophthalmic Surgery Society. Drug waste significantly increases the costs and carbon footprint of ophthalmic surgery. Surgical facilities should be permitted to use topical drugs in multidose containers on multiple patients until the manufacturer's labeled date of expiration, if proper guidelines are followed. Surgical patients requiring a topical medication not used for other patients should be allowed to bring that partially used medication home for postoperative use. These recommendations are based on published evidence and clarification of policies from multiple regulatory and accrediting agencies with jurisdiction over surgical facilities. Surveys suggest that most ambulatory surgery centers and hospitals performing cataract surgery are wasting topical drugs unnecessarily.

ABSTRACT

IMPORTANCE: AGN-190584 (Allergan, an AbbVie company) is an optimized topical formulation of pilocarpine hydrochloride, 1.25%, designed for managing presbyopia and enhanced with a proprietary vehicle. OBJECTIVE: To evaluate the efficacy and safety of pilocarpine hydrochloride, 1.25%, in individuals with presbyopia. DESIGN, SETTING, AND PARTICIPANTS: This vehicle-controlled, participant- and investigator-masked, randomized, phase 3 clinical study, GEMINI 1, enrolled individuals with presbyopia, aged 40 to 55 years, at 36 sites in the United States from December 21, 2018, to October 31, 2019. Analysis took place between February 2020 and December 2021. INTERVENTIONS: AGN-190584 or the AGN-190584 formulation vehicle was administered bilaterally, once daily for 30 days. MAIN OUTCOMES AND MEASURES: The proportion of participants with improvement of 3 or more lines in mesopic, high-contrast, binocular distance-corrected near visual acuity (DCNVA) at hours 3 and 6 on day 30 were the primary and key secondary efficacy end points, respectively. Safety measures included adverse events. RESULTS: Of 323 participants who were randomized, 235 (72.8%) were female and 292 (90.4%) were White. The mean (SD) age was 49.6 (3.5) years, and the baseline mean (SD) mesopic DCNVA was 29.2 (6.3) letters. A total of 163 individuals were randomized to AGN-190584 and 160 were randomized to vehicle. GEMINI 1 met its primary and key secondary efficacy end points. On day 30, hour 3, the percentage of participants with improvement of 3 or more lines in mesopic DCNVA was 30.7% (50 of 163) in the AGN-190584 group and 8.1% (13 of 160) in the vehicle group (difference, 22.5% [95% CI, 14.3%-30.8%]; adjusted P < .001). At hour 6, those percentages were 18.4% (30 of 163) and 8.8% (14 of 160), respectively (difference, 9.7% [95% CI, 2.3%-17.0%]; adjusted P = .01). At hour 8, the between-group difference in 3 or more lines of mesopic DCNVA gains was not statistically significant, but clinically relevant prespecified outcome measures demonstrated AGN-190584 superiority to vehicle in least-squares mean (SE) mesopic DCNVA change from baseline at hour 8 (5.4 [0.51] vs 3.6 [0.52] letters; P = .009) and photopic distance-corrected intermediate visual acuity at hour 8 (3.9 [0.44] vs 2.4 [0.45] letters; P = .01) and hour 10 (3.5 [0.46] vs 1.7 [0.47] letters; P = .004). No participants with mesopic DCNVA improvement of 3 or more lines at hour 3 had losses of more than 5 letters in mesopic, high-contrast, binocular-corrected distance visual acuity. The onset of effect was at 15 minutes. AGN-190584 demonstrated an acceptable safety and tolerability profile. CONCLUSIONS AND RELEVANCE: AGN-190584 demonstrated superiority over vehicle in mesopic DCNVA on day 30, hours 3 and 6, with an acceptable safety profile. AGN-190584 is a safe and efficacious topical therapy for presbyopia through 30 days. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03804268.

ABSTRACT

PURPOSE: To present the 5-year results of the HORIZON trial comparing cataract surgery (CS) combined with an intracanalicular microstent with CS alone. DESIGN: Prospective, multicenter, controlled randomized clinical trial. PARTICIPANTS: Patients with cataract and primary open-angle glaucoma treated with 1 or more glaucoma medications, washed-out diurnal intraocular pressure (DIOP) of 22 to 34 mmHg, and no prior incisional glaucoma surgery. METHODS: Eyes were randomized 2:1 to receive a Hydrus Microstent (HMS; Ivantis, Inc) or no stent after successful CS. MAIN OUTCOME MEASURES: Intraocular pressure (IOP), glaucoma medication use, repeat glaucoma surgery, visual acuity, visual field, procedure-related adverse events, and corneal endothelial cell counts. RESULTS: Three hundred sixty-nine eyes were randomized to HMS treatment, and 187 eyes were randomized to CS only. Study groups were well matched for preoperative IOP, medication use, washed-out DIOP, and glaucoma severity. Five-year follow-up was completed in 80% of patients. At 5 years, the HMS group included a higher proportion of eyes with IOP of 18 mmHg or less without medications than the CS group (49.5% vs. 33.8%; P = 0.003), as well as a greater likelihood of IOP reduction of 20% or more without medications than the CS group (54.2% vs. 32.8%; P < 0.001). The number of glaucoma medications was 0.5 ± 0.9 in the HMS group and 0.9 ± 0.9 in the CS group (P < 0.001), and 66% of eyes in the HMS group were medication free compared with 46% in the CS group (P < 0.001). The cumulative risk of incisional glaucoma surgery was lower in the HMS group (2.4% vs. 6.2%; P = 0.027, log-rank test). No clinical or statistically significant differences were found in the rate of endothelial cell loss from 3 to 60 months between the HMS and CS alone groups (P = 0.261). CONCLUSIONS: The addition of a Schlemm's canal microstent in conjunction with CS was safe, resulted in lowered IOP and medication use, and reduced the need for postoperative incisional glaucoma filtration surgery compared with CS after 5 years. Long-term presence of the implant did not affect the corneal endothelium adversely.

ABSTRACT

A 73-year-old man with an ocular history of inactive age-related macular degeneration and chronic angle-closure glaucoma (CACG) in both eyes recently underwent femtosecond laser-assisted cataract surgery/phacoemulsification and intraocular lens (IOL) implantation with simultaneous Hydrus microstent (Ivantis, Inc.) implantation in the left eye. Although there was some reported subincisional iris prolapse due to intraoperative floppy iris, the case was otherwise uneventful according to the referring surgeon. Two months postoperatively, he was referred to our office for a myopic surprise of approximately 2.0 diopters (D) in the left eye (Figure 1JOURNAL/jcrs/04.03/02158034-202202000-00022/figure1/v/2022-01-26T192641Z/r/image-tiff). Of note, he has a distant history of acute ACG and complicated cataract surgery in the right eye with a failed trabeculectomy. He subsequently had laser peripheral iridoplasty to pull the iris away from the angle in the right eye (Figure 2JOURNAL/jcrs/04.03/02158034-202202000-00022/figure2/v/2022-01-26T192641Z/r/image-tiff). His topical intraocular pressure (IOP)-lowering medications at presentation included dorzolamide-timolol 1 drop twice daily in the left eye and 1 drop of timolol in the right eye once daily. His past medical history is significant for hypertension and benign prostatic hyperplasia, and his oral medications include Tamsulosin (Flomax), Irbasartan (Avapro), and Atenolol. On examination, he had an UCDVA of 20/20 in the right eye and 20/80 in the left eye, and a BCDVA of 20/20 in the right eye and 20/25 in the left eye. His manifest refraction was plano in the right eye and 1.50 -0.75 × 90 in the left eye. IOP measured 19 mm Hg in the right eye and 26 mm Hg in the left eye. Pupil examination revealed a nonreactive pupil in the right eye and a round sluggish pupil in the left eye without an obvious relative afferent pupillary defect. Extraocular motility and confrontational visual fields were full in both eyes. On slitlamp examination, pertinent findings included the following: 1+ corneal guttata without edema in both eyes; anterior chambers were shallow but adequate in both eyes with scattered peripheral anterior synechiae in the right eye and a uniformly shallow but adequate chamber in the left eye; there was no cell or flare in either eye. Iris findings included a surgical pupil with a fibrotic pupillary membrane, laser iridoplasty scars with scattered temporal transillumination defects (TIDs) in the right eye, and 2.5 clock hours of TIDs and a patent peripheral iridotomy at 1 o'clock in the left eye; lens examination revealed centered posterior chamber IOLs with open posterior capsules in both eyes and lens pitting in the left eye. Pertinent findings on dilated fundus examination included a cup-to-disc ratio of 0.3 in both eyes with good neuroretinal rims and macular examination revealed medium-sized drusen with pigment clumping in both eyes and no active choroidal neovascular membranes. The remainder of the examination was unremarkable. What is the etiology of this myopic surprise? What diagnostic testing will help confirm the diagnosis and what are the best management options for this patient?

ABSTRACT

Postrefractive surgery ectasia is a serious, sight-threatening complication seen after the following procedures: laser in situ keratomileusis, photorefractive keratectomy, small-incision lenticule extraction, radial keratotomy, and/or arcuate keratotomy. Specific risk factors may include age, corneal thickness, degree of refractive error, corneal topographic changes including irregular astigmatism, percent tissue ablation, and residual stromal bed. Biomarkers may be a new option to help indicate who is at greatest risk for ectasia. Visual aids including spectacles or contacts lenses are often required to achieve optimal vision. Collagen crosslinking is the only treatment believed to stop progression of ectasia and prevent keratoplasty. Other surgical options may include topography-guided phototherapeutic keratectomy and intrastromal corneal ring segments. Ultimately, an "ounce of prevention is a pound of cure," so careful preoperative screening and ultimately offering the safest and most effective treatments for patients is arguably the most important job of the refractive surgeon.

ABSTRACT

BACKGROUND: Neurotrophic keratopathy (NK) is a relatively uncommon, underdiagnosed degenerative corneal disease that is caused by damage to the ophthalmic branch of the trigeminal nerve by conditions such as herpes simplex or zoster keratitis, intracranial space-occupying lesions, diabetes, or neurosurgical procedures. Over time, epithelial breakdown, corneal ulceration, corneal melting (thinning), perforation, and loss of vision may occur. The best opportunity to reverse ocular surface damage is in the earliest stage of NK. However, patients typically experience few symptoms and diagnosis is often delayed. Increased awareness of the causes of NK, consensus on when and how to screen for NK, and recommendations for how to treat NK are needed. METHODS: An 11-member expert panel used a validated methodology (a RAND/UCLA modified Delphi panel) to develop consensus on when to screen for and how best to diagnose and treat NK. Clinicians reviewed literature on the diagnosis and management of NK then rated a detailed set of 735 scenarios. In 646 scenarios, panelists rated whether a test of corneal sensitivity was warranted; in 20 scenarios, they considered the adequacy of specific tests and examinations to diagnose and stage NK; and in 69 scenarios, they rated the appropriateness of treatments for NK. Panelist ratings were used to develop clinical recommendations. RESULTS: There was agreement on 94% of scenarios. Based on this consensus, we present distinct circumstances when we strongly recommend or may consider a test for corneal sensitivity. We also present recommendations on the diagnostic tests to be performed in patients in whom NK is suspected and treatment options for NK. CONCLUSIONS: These expert recommendations should be validated with clinical data. The recommendations represent the consensus of experts, are informed by published literature and experience, and may improve outcomes by helping improve diagnosis and treatment of patients with NK.

ABSTRACT

PURPOSE: To review evidence and provide guidelines on intracameral (ICM) injection techniques and monitoring. MATERIALS AND METHODS: A review of published literature on ICM injection and intravitreal injections formed the basis for roundtable deliberations by an expert panel of ophthalmologists. RESULTS: ICM injection as a way to deliver medications is growing in popularity. However, there is limited published literature and no standard approach to best practices for ICM injections, particularly when not accompanying another surgical procedure. Fortunately, there is long clinical experience with ICM manipulation and a large body of evidence surrounding intravitreal injections that has provided important guidance. The expert panel formulates several concrete guidelines and many suggested techniques to help physicians safely and effectively employ ICM injections. CONCLUSIONS: This committee addressed the many considerations surrounding ICM injection of drugs or implants and agree that it is a safe and effective surgical procedure when performed with appropriate training and according to established safe practices.

ABSTRACT

PURPOSE: To assess the safety and effectiveness of Schlemm canal stenting for reducing intraocular pressure (IOP) in combination with cataract surgery in the United States cohort of the HORIZON study. SETTING: Twenty-six clinical sites in the U.S. DESIGN: Prospective clinical trial. METHODS: Eyes with mild to moderate primary open-angle glaucoma (POAG) on 1 to 4 medications, significant cataract, and an unmedicated diurnal IOP between 22 mm Hg and 34 mm Hg after medication washout were randomized 2:1 to receive the Hydrus microstent or no further treatment after successful cataract surgery. Patients were followed for 24 months. Medication washout and diurnal IOP measurements were repeated at 12 months and 24 months. RESULTS: Two hundred nineteen eyes were randomized to microstent implantation and 112 patients to phacoemulsification only. At 24 months, the diurnal IOP was reduced by 20.0% or more in a greater proportion of eyes in the microstent group (78.5% versus 54.5%; P < .001). The mean change in the number of medications was -1.2 ± 0.9 (SD) in the microstent group and -0.8 ± 1.1 in the phaco-only group (P < .001), and 78.5% of eyes and 39.2% of eyes, respectively, were medication free (difference 38.8%; P < .001). CONCLUSIONS: Implantation of a Schlemm canal microstent after phacoemulsification significantly reduced diurnal IOP and medication use compared with phacoemulsification only in patients with mild to moderately severe POAG. The combination procedure was equivalent to cataract surgery alone in terms of visual acuity outcomes and the rate of adverse ocular events.

ABSTRACT

A 2 1/2-year-old girl with a history of bilateral retinoblastoma underwent primary enucleation of the right eye and was referred for further management of persistent tumor in the fellow eye. Previous treatment of the left eye included external beam radiotherapy, systemic chemotherapy, laser photocoagulation, cryotherapy, and direct scleral application of a bare iridium-192 radioactive seed. Examination revealed focal full-thickness necrosis of the left upper and lower eyelid and a large inferonasal viable retinoblastoma tumor with overlying retinal detachment. Systemic chemotherapy and direct laser photocoagulation were administered. Four months after presentation, the patient developed focal scleral necrosis with 360 degrees hemorrhagic choroidal detachment. Enucleation was performed and histopathologic examination demonstrated full-thickness scleral necrosis with adjacent viable retinoblastoma tumor cells. Follow-up examinations showed no evidence of recurrent or metastatic tumor. This case is the first report of scleral necrosis following combined modality treatment of retinoblastoma.

ABSTRACT

PURPOSE: To report factors associated with the use of local anesthesia with intravenous sedation (local anesthesia/sedation) rather than general anesthesia for surgery for open globe injuries in adult reparable eyes. DESIGN: Retrospective, nonrandomized, comparative case series. METHODS: Medical records were reviewed of all patients with open globe injuries repaired at Bascom Palmer Eye Institute between 1995 and 1999. "Adult reparable eyes" (eyes in patients >/=18 years of age, not treated with primary enucleation or evisceration, followed up >/=2 months) were included. RESULTS: In all, 220 eyes of 218 patients met inclusion criteria. General anesthesia was employed in 80 of 200 (36%) and local anesthesia/sedation in 140 of 220 (64%). Patients who had local anesthesia/sedation were significantly more likely to have an intraocular foreign body (31% vs 14%; P =.010, chi-square test), better presenting visual acuity (1.8 logMAR [logarithm of the minimum angle of resolution] units vs 2.5 logMAR units; P <.001, t test), more anterior wound location (75% corneal/limbal vs 65%; P =.003, chi-square), shorter wound length (6.3mm vs 10.8mm; P <.001, t test), and dehiscence of previous surgical wound (26% vs 12%; P =.021, chi-square) and were significantly less likely to have an afferent pupillary defect (22% vs 51%; P <.001, chi-square). There was no anesthesia-related complication in either group. The local anesthesia/sedation group had a shorter mean operating time than did the general anesthesia group (78 minutes vs 117 minutes; P <.001, t test). The general anesthesia group had a longer mean follow-up than the local anesthesia/sedation group (20.2 months vs 13.9 months, respectively; P =.002, t test). Change in visual acuity between the presenting and final examinations was similar for open globe injuries repaired with general anesthesia compared with local anesthesia/sedation (0.94 vs 0.72 logMAR units of visual acuity, respectively; P =.16, t test). CONCLUSIONS: Local anesthesia/sedation is a reasonable alternative to general anesthesia for selected patients with open globe injuries.
