Choroidal neovascularization after laser-assisted in situ keratomileusis following penetrating keratoplasty.

Abstract Purpose: To describe a case of choroidal neovascularization (CNV) after laser in situ keratomileusis (LASIK) following penetrating keratoplasty (PK). Methods: Case report. Results: A 30-year-old man underwent PK in both eyes for bilateral keratoconus in 1997. Two years later, best-corrected visual acuity (BCVA) was 20/40 (−6=−4.50×170°) in RE and 20/20 (−1.50=−0.50×90°) in LE. To reduce the anisometropic defect, LASIK was performed in RE. After surgery, the refractive defect in RE reduced to −1.75×125° and BCVA improved to 20/25. Six months after LASIK the patient presented loss of vision and metamorphopsia in RE due to choroidal neovascularization. BCVA was reduced to 20/200. Photodynamic therapy was performed in RE; 1 year later BCVA was stable at 20/200. Conclusion: Vitreoretinal complications after LASIK occur rarely. The potential relationship between CNV and LASIK is discussed.
