Photorefractive Keratectomy and LASIK After Conductive Keratoplasty: Case Series
Narrative Responses:
Purpose
To report the safety and outcomes of Photorefractive Keratectomy (PRK) and Laser In Situ Keratomileusis (LASIK) in eyes with a history of Conductive Keratoplasty (CK).
Methods
A retrospective chart review was performed on all eyes with a history of CK at a private refractive surgery practice between 2003 and 2012. Eyes that underwent subsequent PRK or LASIK to enhance refractive target were identified. Primary outcomes were achieved target, visual acuity, and complications.
Results
300 eyes were treated with CK. 13 underwent subsequent laser keratorefractive surgery (11 PRK and 2 LASIK). The mean time between CK and PRK/LASIK was 1.2 years. The mean follow-up time following PRK/LASIK was 5.2 months. No major complications were reported in any of the 13 eyes including no cases of ectasia. For procedures targeting improvement of near vision, 11 of the 12 eyes had an improvement in uncorrected near visual acuity and 1 of the 12 eyes had no change. The mean improvement in near vision was -0.30 logMAR units.
Conclusion
Laser keratorefractive surgery with PRK or LASIK appears to be safe and effective in eyes with a history of prior conductive keratoplasty.
