Abstract Details


To evaluate the safety and efficacy of CXL followed by refractive lens exchange (Toric IOL) in patients with Pellucid Marginal Degeneration (PMCD)


Retrospective case series of patients with PMCD who underwent CXL and toric IOL at Centre for Sight New Delhi


CXL was performed with the epithelium off method. Toric IOL was performed 6 months or later post CXL once the refraction and topography were stable. UCVA, BCVA, Refraction, Topography (Pentacam) was recorded pre-op and at 1, 3, 6 and 12 months post-op.


5 eyes of 5 patients with mild to moderate PMCD underwent CXL followed by Toric IOL. Mean age of patients was 57+/- 5.6 years. Mean follow up was 12+/- 3.4 months. Mean Sim K pre-op was 47.06 +/- 3.22 which reduced to 45.76 +/- 2.74 at last follow up. Mean pre-op Kmax was 57.44+/-5.91 which reduced to 54.52+/- 6.61. Mean pre-op sphere and cyl were -5.5 +/- 6.61 and 4.0+/-1.5, which reduced to -0.8+/-0.53 and 1.6+/-0.66 respectively. Mean UCVA pre-op was 1.12 +/-0.15 logMAR which improved to 0.4+/-0.15 logMAR. No complications were noted in our series.


CXL followed by Toric IOL is an option for stabilizing the progression and optically rehabilitating the patients with mild to moderate PMCD.
