Toric Collamer Copolymer IOLs After CXL in Eyes With Keratoconus or Ectatic Corneas
Narrative Responses:
Purpose
to evaluate refractive outcome of phakic Visian toric ICL following collagen cross linking in eyes with keratoconus and ectatic corneas
Methods
A retrospective study on 9 eyes who underwent phakic Visian toric ICL implantation following collagen cross linking for keratoconus or post-LASIK ectasia. (5 patients: 3 females , 2 males), mean age was 27.7 ± 2.5 (25–3),mean subjective refraction was: Sphere: -5.4 ± 4.25 D (0.00 to -8.50), cylinder: -4.0 ± 1.4 D (-2.50 to -5.50). The mean best spectacle-corrected visual acuity prior to ICL implantation was 0.6 ± 0.2 (0.4–0.8).
Results
All eyes gained one or more lines of uncorrected visual acuity (UCVA). Mean uncorrected visual acuity improved to 0.82 ± 0.22 (0.6–1.0). Mean spherical equivalent decreased from -6.35 ± 3.60 to -0.65 ± 0.91 D, and mean cylinder decreased from 3.45 ± 1.77 to 1.32 ± 0.71 D.
Conclusion
Toric ICL looks to be a promising tool to correct refractive error (high sphere and cylinder) in stabilized keratoconus and/or corneal ectasia cases
