Comparative study of modified Blumenthal and Ruit technique for manual small- incision cataract surgery (MSICS)
Journal Title: MedPulse -International Medical Journal - Year 2015, Vol 2, Issue 10
Abstract
Aim: To compare the efficacy and visual results of the modified Blumenthal and Ruit techniques for manual small-incision cataract surgery (MSICS). Methodology: This was a prospective, non-randomized comparison of 129 patients with senile cataracts scheduled to undergo routine cataract surgery via either a superior scleral tunnel incision, i.e., the Blumenthal technique (group 1, n = 64) and a temporal sderal tunnel incision, i.e., the Ruit technique (group 2, n =65). MSICS and intraocular lens implantation were performed through an unsutured 6.5- to 7.0-mm scleral tunnel incision. Uncorrected and corrected visual acuity, intraoperative and postoperative complications, and surgically induced astigmatism calculated by simple subtraction were compared. Patients were examined at 1 day, 1 week, 1 month, and 3 months after surgery. Results: Both groups achieved good visual outcome with minor complications. Three months after surgery, the corrected visual acuity was 0.73 in the Blumenthal group and 0.69 in the Ruit group (p =0.29). The average (SD) postoperative astigmatism was 0.87 (0.62) diopter (D) for the Blumenthal group and 0.86 (0.62) D for the Ruit group. The mean (SD) surgically induced astigmatism was 0.55 (0.45) D and 0.50 (0.44) D for the Blumenthal and Ruit groups, respectively (p=0.52). Common complications were minimal hyphema and corneal edema. There was no statistically significant difference in the complication rate between the groups (p > 0.05). Conclusion: In MSICS, both the Blumenthal and Ruit techniques achieved good visual outcomes, with low complication rates.
