Purpose:
To report short-term results of LASIK in 4 eyes with the vesicular form of posterior polymorphous dystrophy (PPMD).
Method:
A review was performed of 2 patients with PPMD who underwent bilateral LASIK. Patients were asymptomatic at the time of presentation and had no prior ocular history. Preoperative measurements were made of uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), corneal pachymetry, and endothelial cell density (ECD). All 4 eyes underwent uneventful LASIK. Postoperative measurements of UCVA and BSCVA were performed at follow-up visits 1 day, 1 month, 3 months, and 1 year after surgery, along with pachymetry and ECD measurements at the 3-month and 1-year visits. Results were analyzed.
Results:
At 1 year, all eyes had an UCVA equal to or better than 20/25 and BSCVA equal to or better than 20/20. There was a small mean endothelial cell loss (2.3%) at 1 year. No adverse events were experienced.
Conclusions:
Short-term results indicate efficacy and safety of LASIK on eyes with posterior polymorphous dystrophy. Further study is needed to assess long-term outcomes in a larger study population.
