Abstract
Purpose: To evaluate the postoperative results when using the toric IOL during phacoemulsification. Methods: Retrospective cohort based study on the 95 eyes of 67 patients, selected by a census. Analyzed patients with cataracts who had undergone phacoemulsification placement with AcrySof® toric IOL from january 2010 to december 2012. For analysis purposes, it was considered successful when the residual astigmatism was d”0.75 diopters. The Wilcoxon test for related samples was used to compare non-parametric samples, while the Student T test was used for samples with normal distribution. A p d”0.05 significance level was granted. Results: The average age of the population was 73.00 (±10.87), there was a higher incidence of females (56.8%) and no difference in the side of the affected eye. The average preoperative spherical component was 0.86 (±2.89), since the average cylindrical component was -1.53 (±1.09), with a predominance of the shaft against the rule (51.6%). The logarithmic visual acuity (logMAR) preoperative average was 0.32 (±0.25). The average postoperative spherical component was -0.02 (±0.53). Surgical success was obtained in 71 eyes (74.7%) having a significant decrease (p <0.001) in the cylindrical component and postoperative logarithmic visual acuity, with the respective values of - 0.61 (±0.55) and 0.08 (±0.14), with the remaining axis against the rule (33.7%). Conclusions: The toric lenses were safe and reproducible with regards to postoperative results and therefore an important option for obtaining excellent final refractometric results.
Highlights
The burden of blindness by cataracts is a major challenge for all countries in the developing world[1,2,3]
A rapid change has occurred in the technique used for cataract surgery in all developed countries, with a progressive increase of phacoemulsification and more recently it has been associated with the use of femtosecond laser[5,6,7]
In the period from 2010 to 2012, 95 eyes of 67 patients who were undergoing phacoemulsification with the implantation of AcrySof® toric IOL for the correction of cataracts were analyzed, and of these, there were a higher incidence of females (56.8%)
Summary
The burden of blindness by cataracts is a major challenge for all countries in the developing world[1,2,3]. One third of the population with around 65 years of age have cataracts in one or both eyes, and about 50% of world blindness is caused by cataracts[2,3,4]. A rapid change has occurred in the technique used for cataract surgery in all developed countries, with a progressive increase of phacoemulsification and more recently it has been associated with the use of femtosecond laser[5,6,7]. These procedures have increasingly gained a refractive purpose, demanding perfect visual results[1,7,8,9]. As for the options for the correction of astigmatism after phacoemulsification there are various models available of toric IOLs, including the AcrySof®(7,13)
