To evaluate the best corrected visual acuity and complication after Pahymetry Assested Lamellar Keratoplasty (PALK ) technique of SHWIND system
Dr Haifa Eye Hospital
17 eyes of 17 patients had moderate and advances keratoconus keratoconus selected . 5 cases with central corneal scar included. The procedure performed using topical anesthesia in 15 cases and local peribulbar anesthesia in 2 patients. All cases had ablation volume of host cornea guided by detailed high resolution pachymetry map of SHWIND-CAM module. Full thickness donor cornea devoid od decemets membrane were sutured to recipient bed. Preoperatively and post operatively Best Spectacle Corrected Visual Acuity(BSCVA), refractive status, endothelial cell count, and intra and post operative complication were evaluated.
No decemets membrane (DM) microperfortae occurred, no patients required convertion to penetrating keratoplasty, and no stromal rejection occurred. Patients followed up from 6 months to 18 months. Uncorrected Visual Acuity (UCVA) improved 12 lines in 75% of cases and 3 lines BSCVA in 62% of cases.
PALK- SHWIND system appears to be safe and effective procedure in keratoconus cases, with shorter surgical time.
