ABSTRACT

PURPOSE: To assess and compare the visual disturbance profiles of 2 extended depth-of-focus (EDOF) intraocular lenses (IOLs). SETTING: Private practice (West Kootenays, British Columbia, Canada). DESIGN: Prospective, randomized, single-surgeon study. METHODS: This was a double-blind prospective study of 138 eyes (69 patients) that underwent bilateral implantation of 1 of 2 EDOF IOLs. Participants were randomized to either the Symfony group or the Vivity group. Outcome measures included Questionnaire for Visual Disturbances; binocular corrected distance visual acuities at distance (6 m), intermediate (66 cm), and near (40 cm); and refractive outcomes. RESULTS: At 3 months postoperatively, 21 patients (60%) reported not experiencing glare in the Symfony group compared with 30 (88%) in the Vivity group, a difference of 28% (P = .008). Reports of experiencing starbursts were also significantly different between the Symfony and Vivity groups (23 participants [66%] Symfony and 30 participants [88%] Vivity; P = .027). In addition, 12 participants (34%) reported "moderate" or "severe" starbursts in the Symfony group compared with 3 (9%) in the Vivity group, a difference of 25% (P = .019). Visual acuities and refractive outcomes were similar between groups. CONCLUSIONS: Both EDOF lenses provide good visual outcomes at distance and intermediate with acceptable near vision. The Symfony group had increased reports of some visual disturbances, notably the frequency, severity, and bothersomeness of starbursts and glare.

ABSTRACT

OBJECTIVE: To compare the visual and patient reported outcomes of 2 presbyopia-correcting intraocular lenses (IOLs). METHODS: A total of 134 eyes (67 patients) that underwent cataract surgery with either a trifocal IOL or an extended depth of focus (EDOF) IOL bilaterally and were assessed 3 months after surgery. Outcome measures were binocular distance-corrected visual acuity at near (40 cm), intermediate (60 cm), and distance (6 m); Akman modified Quality of Life (QOL) Questionnaire-14; and 10% contrast visual acuity at distance and near, with and without glare. RESULTS: Mean binocular logMAR visual acuity (VA) for the PanOptix compared with the Symfony lenses: distance-corrected near VA, 0.054 versus 0.228; distance-corrected intermediate VA, 0.019 versus 0.063; and distance-corrected distance VA, -0.016 versus -0.021. The QOL questionnaire showed that 62% of the PanOptix group and 48% of the Symfony group had little or no difficulty with all QOL-related tasks. In a multivariable model controlling for pupil size and angle kappa (chord mu distance, right eyes), the differences were -0.005 (range, -0.03-0.02) and 0.165 (range, 0.12-0.21), respectively. Also, 10% contrast acuity was comparable in the 2 different lenses and was unaffected by glare. CONCLUSIONS: Binocular distance-corrected near VA was significantly better in the PanOptix group (p < 0.0001). This result remained statistically significant after controlling for pupil size and chord mu distance (p < 0.001). Intermediate and distance VAs were similar between the 2 groups. QOL scores were higher in the PanOptix group.

ABSTRACT

OBJECTIVE: To assess the value of routine polymerase chain reaction (PCR) analysis on intraocular fluid from patients presenting with a first episode of suspected active infectious posterior uveitis in a population with a high prevalence of human immunodeficiency virus infection. DESIGN: Retrospective, interventional case series. Participants. 159 consecutive patients presenting at a tertiary care hospital over a five-year period. METHODS: PCR analysis was performed for cytomegalovirus, varicella zoster virus, herpes simplex virus types 1 and 2, Toxoplasma gondii, and Mycobacterium tuberculosis. RESULTS: PCR analysis confirmed the initial clinical diagnosis in 55 patients (35%) and altered the initial clinical diagnosis in 36 patients (23%). The clinical diagnosis prior to PCR testing was nonspecific (uncertain) in 51 patients (32%), with PCR providing a definitive final diagnosis in 20 of these patients (39%); necrotizing herpetic retinopathy and ocular toxoplasmosis were particularly difficult to diagnose correctly without the use of PCR analysis. CONCLUSION: The clinical phenotype alone was unreliable in diagnosing the underlying infectious cause in a quarter of patients in this study. Since the outcome of incorrectly treated infective uveitis can be blinding, PCR analysis of ocular fluids is recommended early in the disease even in resource poor settings.

ABSTRACT

OBJECTIVE: To determine whether there is a statistically significant difference in the surgical outcome of everting sutures (ES) alone versus everting sutures with a lateral tarsal strip (ES+LTS) in the treatment of involutional entropion. DESIGN: Prospective randomized comparative trial. PARTICIPANTS: Sixty-three patients with primary involutional lower eyelid entropion were enrolled in the study. The age range was 54 to 94 years, with a mean age of 77 years. Baseline characteristics of the comparative groups were similar. METHODS: Patients requiring primary surgical repair for involutional entropion were selected, and those providing informed consent were randomized for surgery. Thirty-six patients were randomized to ES alone, and 27 patients were randomized to ES+LTS. Patients were evaluated at 3 weeks and 6, 12, and 18 months postoperatively. MAIN OUTCOME MEASURES: Successful surgery was defined as a normal eyelid position at rest and inability to induce entropion on tetracaine provocation testing at or before the 18-month follow-up visit. RESULTS: Eight patients were lost to follow-up (7 had ES alone). Of the 55 patients with complete follow-up data, there were 6 failed procedures in the patients who underwent ES alone and no failed procedures in the patients who underwent ES+LTS (P = 0.02). CONCLUSIONS: These data provide strong evidence that success rates at 18 months are higher in patients treated with ES+LTS procedure compared with ES alone.
