Conductive Keratoplasty to Correct Residual Hyperopia and Astigmatism after Cataract Surgery

Purpose: to present conductive keratoplasty (ck) as a new procedure to correct residual hyperopia and astigmatism after phacoemulsification surgery and to evaluate its predictability, safety and stabilitymethods: fifteen eyes of 13 patients with preoperative hyperopia +0.75 to +3.00 d and or astigmatism -0.75 to -3.00 d were enrolled into the study and underwent ck treatment. at the 1st and 3rd month follow-ups, near and far uncorrected visual acuity (ucva) and best corrected visual acuity (bcva), refraction, and in 6th month contrast sensitivity was also considered.results: in six months follow-up uncorrected visual acuity far (ucvaf) 20/40 or better increased from 10 eyes preoperatively to 12 eyes postoperatively. uncorrected visual acuity near (ucvan) 20/40 or better increased significantly from no case to 8 eyes postoperatively. mean manifest sphere (ms) preoperatively was 1.5 d (±0.75) which decreased to 0.05 d (±0.7) postoperatively. mean manifest cylinder (mc) preoperatively was -1d (±0.8) which was decreased slightly to -0.8 d (±0.5). manifest refractive spherical equivalent (mrse) preoperatively was 1 d (±1) which decreased to -0.3 d (±0.83) postoperatively. there was one eye with loss of more than 2 lines of best corrected visual acuity far (bcvaf) and we had no case of 2 lines loss of best corrected visual acuity near (bcvan) during six months follow-up. no significant change occurred during 3rd to 6th months follow-up.conclusion: ck appears to be safe, effective and stable for correcting low to moderate hyperopic after cataract surgery, but more predictable nomogram is needed to correct postoperative astigmatism
