Objective: To compare the visual outcomes and complications of planned and unplanned manual small incision cataract surgery (MSICS) using Ruit technique in cataract patients.

Materials and Methods: The medical records of 3,107 eyes for 2,642 patients with cataracts who underwent MSICS using the Ruit technique at Nan Hospital between January 2016 and April 2023 were retrospectively reviewed. MSICS used a temporal scleral tunnel incision. All 3,107 surgeries were performed by a single surgeon. Out of these 908 eyes of 719 patients, 411 eyes missed the six-week follow-up, the data were incomplete on 195 eyes, 58 eyes underwent combined ocular procedures, and 244 eyes had preoperative vision impairing pathology or previous ocular surgeries. Medical records of 2,199 eyes from 1,923 patients were analyzed, including data on preoperative and postoperative uncorrected visual acuity (UCVA), operative time, intra- and postoperative complications, and astigmatism at the second and sixth weeks after surgery.

Results: MSICS using Ruit technique was performed on 2,199 eyes of 1,923 patients. Both groups achieved excellent surgical outcomes with low complication. The postoperative UCVA at the sixth-week follow-up was 20/70 or better in 96.2% (1,467 out of 1,526 patients) in the planned group and 94.7% (637 out of 673 patients) in the unplanned group. At the sixth week after treatment, the median postoperative astigmatism of both groups were –1.0 (IQR –1.5 to –0.5) D. Hyphema was the most frequent intraoperative complication found in both groups, equating to 5.9% (90 out of 1,526 patients) in the planned group and 8.2% (55 out of 673 patients) in the unplanned group. There was no significant difference in the visual results and complication rates between the groups (p<0.05).

Conclusion: The present study demonstrates that cataract surgery in the unplanned group was safe, and the outcomes in terms of visual results and complications were comparable to those of the planned group. The findings revealed that favorable visual outcomes could be achieved with Ruit technique MSICS.
