To assess astigmatism management in cataract surgery using toric intraocular lenses (IOL).
Hospital Dos de Maig, Barcelona; Hospital Quiron, Barcelona.
Observational retrospective study. Cataract patients with corneal astigmatism over 3 diopters who underwent facoemulsification and toric IOL insertion were assessed. Preoperative and postoperative refraction were compared. Three different models of IOL were used for the surgeries and refraction change, visual acuity improvement and eventually lens related adverse effects were compared among the 3 different types of IOL used.
A total of 30 eyes were studied and no major surgical related complications were observed. Mean preoperative queratometric astigmatism was 5.62 diopters (D), standard deviation (SD) 2.64D. Average visual acuity improvement after surgery was around 0.4 in Snellen test. Mean decrease in refractive astigmatism was 2.5D (SD 1.37D). Mean postoperative spherical equivalent was +0.18D (SD 0.89D). No significant differences were found depending on the type of IOL used in the surgery.
Toric IOL insertion is a safe and effective way to correct astigmatism in patients undergoing cataract surgery.
