Analysis of Our Results With Toric Collamer Copolymer IOL
To evaluate the outcome of patients undergoing toric ICL surgery.
Data of patients who underwent Toric ICL implantation from April 2013 to August 2013 were retrieved from the electronic medical records. All patients underwent refraction, and manual keratometry. Corneal thickness and AC depth were obtained from topography data of the Allegro Wavelight Oculyzer. The White to White measurements were obtained with the digital calipers. This data was sent to Staar Surgical company for the ICL power calculation. All patients also underwent non contact specular microscopy by Tomey specular microscope. The predictability, safety and efficacy of the procedure, the statistical significance of planned versus achieved visual outcomes were measured.
Fifty eyes of 29 patients, age group 17 to 40 (Mean: 24.26±4.68 yrs) were analyzed. Mean follow-up was 8.08 ± 2.70 mos. The preop refractive error ranged -4.00 D Sph to -16.25 D Sph (-9.21±3.89 D) and -1.00 D Cyl to -6.00 D Cyl. (-2.44±1.27D). The preop CCT values ranged 439 to 564 µ. The mean postop sph refractive error was -0.05 ± 0.20 D. The mean change in sph equivalent was -9.15 ± 3.89 D. The mean postop astigmatism was -0.31 ± 0.79D. The mean change in Dcyl was -2.17 ± 1.22D. No residual sph refractive error of more than 1D was noted. 3 patients had a residual of more than 1.0 Dcyl. No drop in BCVA occurred. 2 eyes needed repositioning of ICL (Injury), with final BCVA of 20/20.
Toric ICL procedure is safe and efficacious in patients where laser vision correction is not recommended.
