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 stability

Methods : 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.
