Our experience with toric intraocular lenses implantation

Рurpose. To analyze the results of cataract phacoemulsification with implantation of toric intraocular lenses. Methods. We conducted a retrospective analysis of the results of cataract phacoemulsification with concomitant regular corneal astigmatism of 1.5 D or more. 32 patients (42 eyes) were implanted with toric intraocular lenses: 11 MX 60T lenses (BAUSCH+LOMB) and 31 Torica aAY lenses (HumanOptics). Results. Intraocular lens rotation less than 5 ° was recorded in 40 eyes (95.2 %). In 2 patients, the deviation of Torica aAY lenses was 10–15 °, which required their surgical reposition. All patients achieved an increase in uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA). UCVA after surgery increased by an average of 0.5 (from 0.13±0.03 to 0.63±0.08), and then remained stable. BCVA increased by 0.33 (from 0.37±0.06 to 0.7±0.06) in the early postoperative period, and by another 0.09 (0.79±0.04) in the late period. Mean value of the spherical component of refraction decreased in the early postoperative period by 4.1 D (from 5.05±0.45 to 0.94±0.22), in the late period a slight increase by 0.09 D was recorded. The value of the cylindrical component decreased after the operation by an average of 2.24 D (from 3.31±0.22 to 1.07±0.37), further a decrease by another 0.1 D was observed. Conclusion. The implantation of toric intraocular lenses is a relatively inexpensive, technically uncomplicated, effective and safe method of cataract surgery and associated corneal astigmatism correction. Key words: phacoemulsification; astigmatism; toric intraocular lens.
