Purpose:
Investigate the efficacy and safety of coaxial microincision cataract surgery (CO-MICS) after LASIK, photorefractive surgery (PRK), redial keratotomy (RK) and corneal transplanting.
Setting:
The S. Fyodorov Eye Microsurgery Complex - Federal Budget State Institution, Moscow, Russia
Methods:
24 patients (32 eyes) were examined. They all underwent cataract extractions on Stellaris (B+L) phaco unit. Previously corneal surgery was performed 14±5 years ago. The patients were divided into three groups. The fist group included 9 patients (14 eyes) after LASIK and PRK, the second group - 10 patients (12 eyes) after RK, the third group - 5 patients (6 eyes) after penetrating corneal transplantation. Examination before and two months postoperatively: keratopachimetria, Visante OCT, endothelial cell loss, keratotopography were made. In all cases, cataract density was from the first up to the second degree. For CO-MICS we performed main scleral incision by Mani arcade 1.8 keratome. During the operation BSS level was less than 80cm. OVD combination Viscoat and Provisc was used.
Results:
The endothelial cell loss after CO - MICS in 1, 2 and 3 group was 5.21%, 4.98%, 9.24% to 1 month after CO-MICS surgery. Thickness of the cornea in the 1;2;3 groups was preoperatively: 405±40 mm; 557±45mm; 587±60mm. 1 month after surgery in 1, 2 and 3 group 427±25 mm.; 568±50mm; 612±55mm. Visante OCT investigations don't verify any scare rupture. Corneal topography has not changed mainly. Post-operative 1 month induced astigmatism was 0.37±0.15 D.
Conclusions:
CO - MICS with scleral access Stellaris (B+L) after previous corneal surgery is the safety and effective way to remove cataracts, with 1-2 density. The use of scleral arcade incision 1mm from the limbus does not lead to corneal scarring breaks during surgery and does not cause the induced astigmatism. FINANCIAL DISCLOSURE?: No
