Corneal opacity and cataract: triple procedure versus secondary approach.
OBJECTIVE
To determine the efficacy of planned secondary cataract surgery after keratoplasty.


METHODS
Twenty patients (22 eyes) with simultaneous corneal pathology and cataract were enrolled in a prospective, interventional, case-matched, nonrandomized comparative trial. Penetrating keratoplasty (PKP) and extracapsular cataract extraction (ECCE) with IOL insertion (triple procedure) were performed in 11 eyes, and planned phacoemulsification (PEA) with IOL insertion after PKP was performed in 11 case-matched eyes.


RESULTS
There were 10 eyes (91%) within +/-2.0 D of expected values in the secondary PEA group versus 5 patients (45%) in the triple procedure group. No difference was observed in endothelial cell density after 1-year follow-up.


CONCLUSIONS
Planning for secondary PEA in PKP patients with cataracts is a safe and reliable procedure to obtain less post surgical refractive error. Performing a two-stage intervention has no effect on corneal endothelial viability after 1 year.
