Abstract
Purpose: To study clear lens extraction and posterior chamber intraocular lens implantation outcomes and safety in correction of high myopia.
Patients and Methods: Medical records of 29 patients (40 eyes) who underwent clear lens extraction with posterior chamber IOL implantation to treat high myopia (Axial length > 26.6) were retrospectively reviewed. Visual acuity and refractive error were assessed before and after surgery, and preoperative, intraoperative, and postoperative complications were also recorded.
Results: The mean postoperative follow-up period was 10.9 ± 4.63 months (Range, 6 - 19 months). The mean final best corrected visual acuity of 6/10 ± 2/10, was better than preoperative best corrected visual acuity (Mean: 2/10 ± 1/10). Final spherical equivalent (SE), (Mean = - 0.95 ± 0.45 diopters, Range - 0.25 to - 2 D) was better than preoperative SE (Mean = 19.41 D ± 5.31, Range 9 to 31 diopters). No cases of intraoperative complications occurred. The only postoperative complication was posterior capsule opacification in one eye 18 months after surgery and biometric error of (2 D) occurred in one eye.
Conclusion: Clear lens extraction with posterior chamber IOL implantation in high myopic eyes has good outcomes with acceptable predictability, improvement in best corrected visual acuity and low rate of complications.
