Abstract Details


To assess the quality of the optical system of the eye and quality of vision after phacoemulsification with implantation of the aberration-free IOL (Incise, Valeant) in patients underwent previously keratorefractive surgery.


Moscow, Eye Center “East Sight Recovery”.


34 eyes of 18 patients after keratorefractive surgery underwent femtosecond laser-assisted phacoemulsification. 14 patients underwent radial keratotomy 20-25 years ago, 4 patients were after Lasik. In I group ( 16 eyes) 8 patients received an aberration-free IOL Incise (Valeant). In II group (18 eyes) 10 patients received aspheric IOLs. Preoperative ophthalmic examination included corneal topography with Orbscan II and wavefront analysis with Zywave aberrometer ( Valeant). IOL calculation was performed with Barrett Universal II formula. Postoperatively, refractive outcomes, uncorrected and best corrected visual acuity were determined. Pre- and postoperatively wavefront aberrometry were studied to assess the quality of vision.


Follow-up period was 3-10 months. In both groups, best corrected visual acuity 0.8 and better was achieved in 80% with. Target refraction (+0,5 D) was achieved in 72 % cases. In 3 months the mean value of HOAs in the first group was 0,69 µm, total aberrations -1,05 µm. In the second group HOAs -1,08 µm, total aberrations -1,87 µm. The patients satisfaction was higher in Incise IOL group.


No significant difference was found between IOLs in terms of visual acuity. Asheric IOL implantation in patients after keratorefractive surgery may increase total aberrations of the eye. The aberration-free IOL Incise has been shown lower level of HOAs and total aberrations and higher level of satisfaction in patients after keratorefractive surgery.
