Analysis of the the nature of clinical and functional changes after toric IOLs implantation in the eyes with previously performed radial keratotomy

Сenter of Eye Microsurgery VOKA, Minsk, Belarus

The results of surgical treatment for cataracts or with a refractive aim of 20 patients (26 eyes) with a previously performed radial keratotomy are presented. Monofocal toric IOL SN6AT3-8 (Alcon) were implanted. The lens power was calculated using the following formulas: Holladay II corrected for radial keratotomy, Hoffer Q, Double-K Holladay 1, Barrett True K. The toric component was calculated using the Barrett formula. Uncorrected distance VA before surgery: 0.2 ± 0.17, best corrected VA 0.48 ± 0.22, refraction sph -1,67 ± 3.37; cyl – 1.05 ± 1.4

As a result of surgical treatment an improvement in the following clinical and functional results was obtained: refraction, uncorrected and maximally corrected visual acuity. The following results were obtained in 6 months after the surgery: uncorrected distance VA 0.62 ± 0.18, best corrected VA 0.77 ± 0.15, refraction sph -0.3 ± 1,06; cyl -1.03 ± 0.51.

Toric IOL implantation SN6AT3-8 (Alcon) in eyes with previously perforemed radial keratotomy helps to improve visual acuity in most of the cases. No advantages were noted in the application of the mentioned above formulas in achieving the target refraction. The results remained high during the observation period from 6 to 26 months. The probability of refractive errors is bigger in eyes with high corneal irregularity.
