Study finds less endophthalmitis after sequential bilateral cataract surgery than unilateral surgery

A survey of members of the International Society of Bilateral Cataract Surgeons shows no cases of bilateral endophthalmitis occurring among 95,606 eyes (a sample size more than six times larger than the ESCRS endophthalmitis study) that had immediately sequential bilateral cataract surgery. The overall rate of postop infection was calculated as 1 in 5,759. The authors also conducted a literature review to determine the recent incidence of postop endophthalmitis in unilateral cataract surgery with and without the use of intracameral antibiotics. Infection rates were significantly reduced with intracameral antibiotics to 1 in 14,352 cases.

Aspheric IOLs appear to provide better visual function at night

This prospective, multicenter, double-blind study compared visual acuity and visual quality in 39 patients implanted with a spherical IOL in one eye and an aspheric IOL in fellow eyes. While visual acuity was similar between the two groups, the aspheric group achieved lower levels of higher order aberrations. Regarding contrast sensitivity, the aspheric IOL showed better performance under mesopic conditions, especially with glare. There was no difference under photopic conditions.

Light-adjustable IOL demonstrates stability over time

This prospective, nonrandomized trial included 122 eyes implanted with a light-adjustable IOL that can be adjusted postoperatively using ultraviolent radiation. At 18 months follow-up, residual spherocylindrical errors up to 2.25 D in sphere and -2.75 D in cylinder were successfully corrected, with 98 percent of patients within ± 0.50 D of the intended correction, and 79 percent of eyes experiencing 0 D of residual sphere. Results were stable over 18 months. Final refraction achieved was 0.03 ± 0.17 D in spherical equivalent refraction. One of the keys to success is patient compliance with wearing UV protective spectacles until lock-in is performed.
