Abstract:
We retrospectively studied 26 eyes of 16 patients(male :9 patients, female:7 patients, mean age:39.3 years)who received clear lens extraction by phacoemulsification and low-power posterior chamber intraocular lens implantation. To investigate the effectiveness of clear lens extraction, visual acuity, refractive results, and intraoperative and postoperative complication were analyzed. The mean follow-up was 14.7 months. For reasons of lattice degeneration, retinal tear, or hole, we performed argon laser photocoagulation before clear lens extraction in 84.6% of patients. The IOL power was calculated using the SRK/T formula. Uncorrected visual acuity improved in all cases, with 65.4%of eyes achieving 20/40 or better and 23.1%, 20/25 or better. Corrected visual acuity improved in all cases, the percentage of eyes achieving corrected visual acutiy of 20/40 or better increased from 69.2%preoperatively to 100%postoperatively and the percentage of 20/25 or better, from 3.8%to 80.8%.The mean postoperative spherical equivalent was -15.85D (-10.25 to -23D), 50%of eyes were within 1.0D of the goal diopter and 100%were within 2.0D of the goal diopter.No intraoperative complications occurred.During the follow-up, 42.3% of eyes developed mild posterior capsule opacification and 1 eye(3.8%) received a YAG laser posterior capsulotomy 22 months postoperatively. No retinal tear, retinal detachment, or cystoid macular edema was observed. Clear lens extraction with low-power IOL implantation was effective for the correction of high myopia but additative cases and longer follow-up periods are needed to fully assess the complication.
