Predictive Factors and Management of Macular Edema after Retropupillary Iris-Claw Intraocular Lens Implantation in Aphakia: National Multicenter Audit-Report 2.

The aim of this multicenter, national clinical audit is to evaluate the predictive factors and management of postoperative macular edema (ME) after retropupillary iris-claw intraocular lens (RICI) implantation and pars plana vitrectomy (PPV). Preoperative, surgical and postoperative data were collected. Number and type of intravitreal injections (IT) administered (anti-VEGF or dexamethasone implant), visual acuity (VA), intraocular pressure (IOP) and central retinal thickness (CRT) assessed by OCT were collected at 1, 3, 6 and 12 months. From 325 eyes (325 patients), 11.7% (38/325) developed postoperative ME. Previous complicated cataract surgery with no capsular support was the only significant predictive factor for developing postoperative ME (OR 2.27, 95% CI 1.38-4.52, p = 0.02) after RICI implant. Mean time to ME development was 11.4 ± 10.7 weeks, and mean CRT peaked at 3 months follow-up. Different treatment options were non-steroidal anti-inflammatory (NSAIDs) drops (31.6%, 12/38), dexamethasone (DEX) implant (50%, 19/38), anti-VEGF (7.9%, 3/38) or combined IT (10.5%, 4/38). Cumulative probability of ME resolution was higher in the group treated with IT than in the group treated with topical NSAIDs (85.2% vs. 58.3%, p = 0.9). Performing RICI implantation after complicated cataract surgery is a risk factor for the development of postoperative ME. DEX implants may be an effective treatment for postoperative ME in these cases.

RETROPUPILLARY IRIS-CLAW INTRAOCULAR LENS AND PARS PLANA VITRECTOMY IN APHAKIA MANAGEMENT: A National Multicenter Audit.

PURPOSE: To evaluate the outcomes and safety of retropupillary iris-claw intraocular lens implantation and associated pars plana vitrectomy. METHODS: Multicenter, national audit of 325 eyes (325 patients). Demographics, surgical details, and complications are described. Visual acuity, intraocular pressure, and central retinal thickness assessed by optical coherence tomography were collected at 1, 3, 6, and 12 months after surgery. Kaplan-Meier curves were created to assess the cumulative probability of postoperative visual acuity and intraocular pressure levels, macular edema development, and corneal decompensation. RESULTS: The cumulative probability of the final visual acuity ≤0.3 logarithm of the minimum angle of resolution (≥20/40 Snellen) was 75.6% at 12-month follow-up. The probability of intraocular pressure >21, ≥25, and ≥30 mmHg was 48.1%, 33.1%, and 19.0%, and the probability of intraocular pressure-lowering drops was 50.9% at 12 months. Glaucoma surgery was required in 4.3% of the eyes (14/325). The cumulative probability of macular edema was 20.5% at 12 months and was greater in complicated cataract surgery than in intraocular lens-luxation eyes (26% vs. 16.7%, P = 0.04). Corneal transplantation was required in 2.8% of the eyes (9/325). CONCLUSION: This study on 325 eyes with aphakia or intraocular lens dislocation managed with the retropupillary iris-claw intraocular lens technique provides clinical outcomes in a real-world scenario, reporting relevant data for patient counseling and preoperative discussions.

Extreme Surgical Maneuvers in Fungal Endophthalmitis.

PURPOSE: To present the different evolution of 2 cases of endophthalmitis caused by Fusarium solani, an aggressive filamentous fungus, depending on the medical and surgical treatment performed. METHODS: We present 2 cases of endophthalmitis caused by Fusarium solani. Topical, intrastromal, intravitreal, and systemic antifungal treatment (natamycin, voriconazole, amphotericin B) failed in both cases. Corneal perforation took place in one of them, being unsuccessfully treated with cyanoacrylate and several amniotic membrane transplants. It became necessary to perform a hot penetrating keratoplasty (PK) in both patients. The lenses were removed, and the microbiological analysis showed their colonization by Fusarium solani. In one of the cases, a second PK and a more aggressive pars plana vitrectomy (PPV) were performed after corneal recurrence detected by confocal microscopy, as well as the following therapeutic intra- and postoperative maneuvers: anterior chamber washing with povidone-iodine 5% for 1 min; iridectomy of the infiltrated regions; aspiration of the fungal colonies with vitrector; several air/fluid/amphotericin/voriconazole exchanges during PPV; endodiathermy and endophotocoagulation of the chorioretinitis foci; and intrascleral angle injections of voriconazole and amphotericin. RESULTS: These were the only cases of endophthalmitis caused by Fusarium attended to at our hospital during the last 10 years. In the case in which PPV was performed without those maneuvers, endophthalmitis rapidly recurred in a more aggressive way, so finally it became necessary to eviscerate the globe. On the other hand, in the patient who underwent PPV with the specific surgical maneuvers and postoperative procedures described above, we could preserve the eye and even a vision of hand motion without an intraocular lens. CONCLUSIONS: The main objectives of these surgical procedures are to control the fungal infection and to preserve the ocular globe. It is essential to eliminate all ocular structures (iris, lens, vitreous, etc.) affected by this strain of fungus in order to reduce the risk of recurrence. When indicated, early surgery with the appropriate maneuvers detailed above may make an evisceration unnecessary and even recover some visual acuity.

DEXAMETHASONE IMPLANT REMOVAL FROM ANTERIOR CHAMBER: SURGICAL TECHNIQUE.

PURPOSE: To describe a surgical technique for complete and safe dexamethasone intravitreal implant (Ozurdex; Allergan, Inc., Irvine, CA) removal from anterior chamber. METHODS: Description of a new surgical technique for Ozurdex removal using a lens injector cartridge. RESULTS: Dexamethasone implant was removed completely from anterior chamber with no damage to corneal endothelium or posterior chamber luxation in a patient with Ozurdex anterior chamber migration. CONCLUSION: Dexamethasone implants can be removed from anterior chamber in an easy, cheap, fast, and save way.

Inadvertent cyclodialysis cleft and annular ciliochoroidal detachment after hyperopic phakic intraocular lens implantation and prophylactic surgical iridectomy.

UNLABELLED: We present the case of a 26-year-old man with severe early hypotony after implantation of the Implantable Collamer Lens phakic intraocular lens (pIOL) in the left eye for hyperopia. To our knowledge, this is the first documented case of cyclodialysis cleft and secondary annular ciliochoroidal detachment after implantation of a pIOL, presumably provoked by a straightforward prophylactic surgical iridectomy. The initial diagnosis was determined using swept-source Fourier-domain anterior segment optical coherence tomography as gonioscopy and ultrasound biomicroscopy did not reveal the cleft. Conservative treatment was not effective. Argon laser photocoagulation resolved the problem. FINANCIAL DISCLOSURE: No author has a financial or proprietary interest in any material or method mentioned.

Efficacy of bevacizumab against interface neovascularization after deep anterior lamellar keratoplasty.

PURPOSE: We report a case of neovascularization at the interface after a deep anterior lamellar keratoplasty and its regression after a single bevacizumab injection. METHODS: Case report. RESULTS: We present a case of neovascularization and bleeding at the interface 2 days after a deep anterior lamellar keratoplasty for herpetic disease that was completely reversed by a single injection of bevacizumab at the interface. CONCLUSIONS: Corneal neovascularization is a typical sign of herpetic disease and one of the most important risk factors that can contribute to corneal graft failure. Close follow-up of patients at risk is necessary to detect and treat this complication as soon as possible to achieve a good outcome. Bevacizumab seems to be a successful and safe therapeutic option.
