Description

Purpose:We examined the visual acuity after phototherapeutic keratectomy(PTK)for the treatment of corneal dystrophies and assessed its implications for cataract surgery.Patients and methods:50 eyes in 32 patients with corneal dystrophies were treated with PTK . Cataract surgeries were performed after PTK in case of 32 eyes of 21 patients. The primary outcome measures were best-corrected visual acuity.Results:18 eyes of 14 patients were performed only PTK. The mean visual acuity of 18 eyes improved from 0.31 to 0.67(p<0.01).Visual acuity improved in 14 eyes out of 18 eyes(77.8%).32 eyes of 21 patients were performed cataract surgery after PTK. The mean visual acuity of 32 eyes improved from 0.26 to 0.58(p<0.01).Visual acuity improved in 26 eyes out of 32 eyes(81.3%).Mean time between PTK and cataract surgery was 4.4±2.6 months.Conclusion:PTK is effective for improving vision in patients with corneal dystrophies, as evaluated at more than 1-year follow-up examination. Cataract surgeries after PTK in those patients were further benefical for improvement of vision and may be useful to perform cataract surgery safely.
