Management of corneal ectasia and cataract following photorefractive keratectomy.

A 42-year-old man was referred to our clinic 18 months after bilateral photorefractive keratectomy (PRK). He had been on topical prednisolone acetate for 12 months because of post-PRK grade 4 haze. On his first visit, visual acuity was limited to light perception in both eyes because of moderate haze, significant corneal ectasia, and a white cataract. A 2-step surgical approach was elected in both eyes. First, a deep anterior lamellar keratoplasty was performed. Six weeks later, phacoemulsification with intraocular lens implantation was performed. Compared with a triple procedure combining penetrating keratoplasty and cataract surgery in 1 stage, the 2-step approach may lower the risk for corneal graft rejection and reduce ametropia.
