Toric IOLs safely correct astigmatism, improve vision
Toric IOL implantation safely corrected astigmatism while improving visual performance and decreasing wavefront error, according to a study.
The refractive cylinder decreased from 2.17 D preoperatively to 0.73 D postoperatively at 180 days; the results were statistically significant (P = .001).
A statistically significant difference was found amid preoperative corneal astigmatism and postoperative refractive astigmatism (P < .05).
LogMAR uncorrected distance visual acuity was 0.20 in 100% of patients and 0.0 in 64% of patients at 180 days postoperatively.
The root mean square of internal coma and trefoil aberrations aimed toward reduction and internal spherical aberration significantly reduced postoperatively (P = .037), the authors reported.
There was no statistical significance for tilting and IOL decentration variation between 30 and 180 days postoperatively.
The study authors said the results warrant longer follow-up and larger studies to evaluate long-term efficacy of toric IOLs in astigmatism correction.
