Outcomes of laser in situ keratomileusis in patients with pigment dispersion syndrome

Purpose: To analyze the outcome of laser in situ keratomileusis (LASIK) in patients with pigment dispersion syndrome (PDS). Setting: Outpatient ambulatory laser vision correction centers. Methods: This noncomparative case series reviewed the medical records of 12 patients (22 eyes) who had clinical features consistent with PDS at the time of the initial preoperative refractive evaluation and had LASIK surgery. Results: Twenty eyes (90.9%) of 11 patients had an uneventful course after LASIK and a good final uncorrected visual acuity (mean follow-up 26 months). One patient (2 eyes) with PDS and suspicion of glaucoma on topical β-blocker therapy had delayed healing, fluctuations in vision, and a lengthy visual recovery. Conclusions: Corneal findings of PDS do not appear to affect the intraoperative or postoperative outcomes of LASIK. However, patients who have PDS in the context of glaucoma and therapy with an intraocular-pressure-lowering agent may experience delayed healing and a less predictable visual outcome.
