Visual Outcome of Clear Lens Extraction (Phacorefractive) in Myopia Above -12.0 Dioptres

Abstract

Purpose: A non-comparative study to evaluate the visual outcome of clear lens extraction (phacorefractive) in myopic eyes of 12 dioptres and above using acrylic foldable intraocular lenses (IOLs).

Material and Methods: The study was conducted in a private setup from Jan 2004 to Dec. 2006. Forty eyes of 20 patients underwent clear lens extraction by phacoemul-sification using single piece acrylic foldable IOL. Twenty eight eyes were of males (70%) and 12 were of females (30%). Their ages ranged between 21 years and 36 years, with mean age of 28.5 years. Myopes of -12 D to -20.0 D with one year stability of myopia and contact lens wearing intolerance were included in this study. Prophylactic 360 degree retinal Argon laser photocoagulation was performed only where it was deemed necessary. All surgeries were performed by the same surgeon and were uneventful.

Results: Preoperative spherical correction was between -12.0 to -20.0 D. Postoperative spherical correction was -0.50 to -2.0 D. Preoperative best spectacle-corrected visual acuity (BSCVA) was 6/12 or better in 50% of the eyes which increased to 70% postoperatively. No vision threatening complications were noted.

Conclusion: Results of clear lens extraction with foldable acrylic IOL implantation are satisfactory and practically acceptable.
