Abstract:
Objective: To evaluate the effect of micro-incision (2.2 mm) coaxial phaco-emulsification with implantation of intraocular lenses on corneal astigmatism, keratometric values, and surgically induced astigmatism (SIA). Materials and methods: In this study we have checked 30 patients who have undergone cataract phaco surgery (microincision) with 2.2mm corneal incision. All participants have gone throw usual preoperative examinations and findings. Phaco-emulsification was followed by intraocular lens implantation via the Monarch II injector with the C cartridge. Uncorrected distance visual acuity, corneal keratometry and corneal astigmatism and SIA were assessed 1, 7 and 30 days after cataract surgery. Results:Mean preoperative visual acuity (BCVA) in 30 patients who underwent phacoemusification with implantation intraocular lens (IOL) through 2,2mm corneal incision was 0.1123 ± 0.0374. On the first postoperative day after surgery, mean uncorrected visual acuity in patients with 2.2mm corneal incision was 0.75 ± 0.0594, on 30th day it was 0.9467 ±0,0306. Key words:microincision phaco; surgical induced astigmatism; corneal astigmatism In this study, we monitored movement of keratometric value, in a short postoperative period of thirty days after cataracts phacoemulsification with intraocular lens implantation through a 2.2mm corneal incision .As expected maximal astigmatism value, so as keratometric, occurred soon after surgery. In the further postoperative course it leads to reduction of keratometric value and grouping values around the mean values. Surgical induced astigmatism on first day after was 1.87±0.906, while seven days after surgery it was 1.36±0,778 and on 30th day after surgery it was 0.85±0.630. Conclusion:Today’s reduction in corneal incision size is trend in modern phaco surgery. Reduction in size of corneal incision by 0,8mm (from 3.0mm to 2.2mm) could give better control of keratometric and astigmatic values after surgery at least in early postoperative period.
