Implantation of the ZSAL-4 IOL in the anterior chamber of phakic eyes was effective and predictable in correcting severe myopia. However, the ZSAL-4 did not prevent pupil ovalization, IOL rotation, or low-grade postoperative uveitis. Improvements in haptic design following our mechanical model could decrease these haptic-related complications.

Our study shows chronic subclinical inflammation between 1 and 2 years after implantation of both IOL types.

Endothelial cell loss during the first year was similar in eyes with Worst-Fechner and Baikoff ZB5M lenses; however, at 2 years after surgery, endothelial cell loss was higher in eyes with Worst-Fechner lenses than it was in eyes with Baikoff ZB5M lenses.

Purpose A comparison of the topographic astigmatism generated after coaxial phacoemulsification (CP) through temporal 2.8 mm incision and biaxial phacoemulsification (MICS) through superioroblique trapezoidal 1.5-2 mm incisions. Setting Centre for Visual Sciences (Instituto de Ciencias Visuales, INCIVI), Madrid, Spain Methods This prospective randomized clinical study included 94 eyes of 64 patients; 43 eyes were operated on through CP and 51 through MICS. Corneal topography was measured before operation, and subsequently after 1, 3, and 6 months. Additionally, a control group (C) of 55 eyes was created (performing two topographies on them); the change in astigmatism was calculated without having performed any surgical procedure. The astigmatic change in the three groups was measured through arithmetic, polar and vector analysis (Alpins method). Results In the vector analysis, results after the first month following surgery were: mean module of the surgically induced astigmatism (SIA) 0.49 ± 0.38 D in CP and 0.48 ± 0.37 D in MICS, while 0.31 ± 0.27 D in group C. Although no statistically significant differences were detected between the two surgical techniques, differences were noted when comparing group C with each of these techniques (Po0.05). The distribution of the SIA axes showed a slight tendency to be located more frequently at around 901 in CP, and at around 501 in MICS. Conclusions The mean module of SIA was similar in CP and in MICS, although the distribution of the direction of such a vector revealed minor differences.

Femtosecond laser cataract surgery is a good addition to cataract surgery despite its few remarkable advantages among experienced phacoemulsification surgeons.

A 33-year-old patient had uncomplicated anterior chamber intraocular lens implantation (Worst-Fechner biconcave myopia lens) to correct high myopia. Immediately after surgery, she developed anterior ischemic optic neuropathy likely associated with increased intraocular pressure and systemic hypotension. To our knowledge, this is the first documented case of anterior ischemic optic neuropathy after anterior chamber intraocular lens implantation to correct high myopia in a phakic eye.

Emulsification of the lens using the Er:YAG laser was effective for performing small incision cataract surgery in eyes with soft and medium nuclei. The small ablation zones created can help prevent damage to surrounding ocular structures. The Er:YAG technique used less ablation energy than US emulsification and did not result in thermal injury.
