Abstract Details



Purpose:

to evaluate advisability of toric IOLs implantation in surgical treatment of complicated cataracts

Setting:

The S.N. Fyodorov Eye Microsurgery Federal State Institution, Volgograd branch

Methods:

there were studied 90 cases (90 eyes) of toric IOLs implantation (Acrysof, Alcon) in mono- and multifocal design. Preoperative examination revealed 84 cases of refractive amblyopia, 3 cases of keratoconus, 4 cases of pupil ectopia. In 13 cases toric IOL was inserted in pediatric patients. Preoperative astigmatism according to findings of keratometry varied in a range from 1,25 D to 6,25 D, refraction differential in central optical zone didn't exceed 1,5 D, noncorrected visual acuity equaled 0,02-0,2. In all the cases phacoemulsification was performed by standard technique with tunnel corneal incision of 2,2 mm. Special attention was paid to corneal marking.

Results:

follow-up period in all the patients was 6-12 months. Cylindrical component according to postoperative refractometry equaled 0,25-1,25 D. Keratometric findings fluctuated within ± 0,25 D from the initial values. NCVA amounted to 0,4-0,9 and remained stable throughout the follow-up period. All the patients were totally satisfied with surgical outcome.

Conclusions:

implantation of toric Acrysof IOL's in eyes with clinically significant astigmatism values provides excellent refractive and functional results, confirmed by refractometry and may be considered as a method of choice in aphakia correction in all age cohorts in eyes with refractive amblyopia and astigmatism, including cases of irregular astigmatism and pupil ectopia.
