Outcomes of toric intraocular lens implantation

Purpose: Evaluate the visual results, refractive correction and intraocular lens stability of the eyes with cataract and greater than and equal to 1.25 diopters (D) astigmatism after phacoemulsification with toric intraocular lens implantation (TIOL) surgery Methods: 24 eyes of 15 patients were included in this retrospective study. Cataract surgery and implantation of TIOL was performed to the patients with cataract and greater than and equal to 1.25 diopters (D) astigmatism. Patients were followed for minimum 6 months. The uncorrected (UDVA) distance visual acuities, residual refraction status and IOL rotation degrees after one day, one week, one month, three months and siz months were evaluated. Results: 24 eyes of 15 patients (10 women, 5 men) with mean age of 65.95 ± 9.40 (50-81) were included. Preoperative mean best corrected visual acuity (BCVA) was 0.38 ± 0.19 logMAR. 6 months after surgery, UDVA was greater than and equal to 0.10 logMAR and mean UDVA was 0.03 ± 0.04 logMAR (0.00-0.15). Also, BCVA was 0.01 ± 0.04 logMAR (-0.10-0.05). Mean preoperative cylindirical refraction value, mean corneal astigmatism and mean residual astigmatism was 2.58 ± 1.07 D (0.75-4.75), 2.34 ± 0.68 D (1.25–3.85) and 0.44 ± 0.18 D (0.25-0.75) respectively. Mean IOL rotation value was measured as 4.16 ± 2.01 º (2-8) at 6 months. Surgically induced astigtmatism (SIA) was 0.39 (0.10 - 1.05). None of our patients were operated for correction of residual astigmatism. Conclusions: TIOL implantation to the eyes with cataract and greater than and equal to 1.25 diopters (D) astigmatism is a convenient option for rotation stability and refractive gain in patients with vision expectation independent of glasses.
