- W1993109961 abstract "A retrospective study to ascertain the management of pellucid marginal corneal degeneration (PMCD).Sixteen patients (average age 42.6 years) presented with PMCD. PMCD was bilateral in 13 and unilateral in 3 patients. Eight eyes underwent surgery. Nineteen eyes were managed non-surgically. Surgery involved corneal wedge excision (WE) (6 eyes), penetrating keratoplasty (PK) (3 eyes) and lamellar thermo-keratoplasty (LTK) (1 eye). Immediate pre-operative average visual acuity (VA) was 6/24, 6/10 and 6/60 with an average pre-operative astigmatism of 11.40 D, 9.75 D and 20.5 D for WE, PK and LTK respectively. After an average post-operative follow-up of 57 months, 66 months and 1 year, the average astigmatism was 8.90 D, 4.63 D and 6.00 D with an average final VA of 6/19, 6/15 and 6/6 for WE, PK and LTK respectively. In the nonsurgical group, at presentation, 40% of eyes had a VA of 6/12 or better. After an average follow-up period of 32.3 months, 80% of eyes had a visual acuity of 6/12 or better. Optical correction was achieved with spectacles and or contact lenses.Surgical correction for PMCD provides poor long-term reduction of astigmatism. Patients with PMCD may be adequately corrected in the long term by the use of scleral fitted gas-permeable contact lenses." @default.
