Özet

In advanced pellucid marginal degeneration (PMD) cases, Lamellar Wedge Resection (LWR) is a method that is used to postpone or eliminate the necessity for allogenic lamellar or penetrating keratoplasty.In this study, we presented the results of LWR and cataract surgeries in two cases, 62 years old with bilateral PMD (case 1) and 83 years old with unilateral PMD (case 2) presenting with acute hydrops.In Case 1, topographic astigmatism (TA) decreased from 20.2 D to 6.3 D, and visual acuity (VA) increased from 1.80 LogMAR to 0.2 LogMAR Snellen chart after all sutures have been removed.In the second year TA increased to 15.2 D and did not change until the end of the 3rd year. In Case 2, TA decreased from 11.6 D to 3.3 D after 28 months of follow-up, and VA increased from 2.1 LogMAR to 0.10 LogMAR level. Monofocal IOL was performed due to the continuous changes in astigmatism in the early period after LWR, resulting in an increase in VA in both cases.
