To evaluate the effect of incision lengths with or without suturing in surgically induced astigmatism for insertion of PMMA or foldable intraocular lenses by phacoemulsification.
Phacoemulsification was performed by the same surgeon for 56 senile cataract patients who have full vision capacity in a randomized prospective trial. Twenty-eight patients received 5.5 mm scleral tunnel incision and PMMA IOLs, half of them sutured with 10.0 vicryl .Another 28 patients received 3.5 mm scleral tunnel incision and folable IOLs, half of them sutured with 10.0 vicryl.Visual acuity (VA) measurement and surgically induced keratometric astigmatism (SKA) calculated by vector analysis were repeated postoperatively on the third day and second month.
Mean VA was not different in the groups.78% had uncorrected VA>= 0.5 on the third day whereas 99% had >= 0.8 corrected VA on the second month. SKA were 1.51±0.83 D for 5.5 mm no-suture, 0.76±0.65 D for 5.5 mm sutured incisions and the difference was significant (p=0.008). SKA of 0.75±0.60 D for 3.5 mm no-suture, and 0.54±0.29 D for sutured 3.5 mm incisions were found, but the difference was not significant. Sutured 5.5 mm incision had no significant difference in SKA from sutured or unsutured 3.5 mm incisions.
5.5 mm incision without suture causes significant SKA whereas suturing 5.5 mm or performing a 3.5 mm incision with or without sutures leads to similar surgically induced astigmatism.Keywords: Cataract, phacoemulsification, astigmatismTurkiye Klinikleri J Ophthalmol 1999, 8:86-89
