PURPOSE: Comparative study of intraoperative and postoperative complications, visual outcomes, and cost-effectiveness between conventional and 4-mm manual small-incision cataract surgery with MVR blade.
METHODS: In total, 600 patients having nuclear sclerosis grade I-IV were operated under peribulbar anesthesia and were divided into two groups of 300 each. In group A (300), conventional small-incision cataract surgery was done, whereas in group B (300), 4-mm manual small-incision cataract surgery was performed through a 4-mm sclerocorneal tunnel. A wire vectis was passed through the 4-mm incision below the nucleus to stabilize it, and a 20-G MVR blade was introduced from 11o'clock limbus and nucleus was bisected into two halves, which were removed through main incision. Cortical wash was given, and foldable IOL was implanted. Intraoperative and postoperative complications between the two groups were compared. Postoperative visual outcome and surgically induced astigmatism between the two groups was studied.
RESULTS: The most common intraoperative complication was hyphema (11.33%) and irido-dialysis (8.00%), whereas postoperatively, striate keratopathy (36.33%) and hyphema (19.33%) were common. Short-term complications such as striate keratopathy, hyphema, and irido-dialysis were significantly more in group B, and long-term results in terms of visual outcome and surgically induced astigmatism were significantly less in group B.
CONCLUSION: Although intraoperative and short-term postoperative complications were observed more in 4-mm manual small-incision cataract surgery, it was found to be more effective in terms of surgically induced astigmatism and final visual outcome. In addition, it is cost-effective as compared to phacoemulsification.
