Summary

The superior rectus bridle suture and wound location do not significantly impact postoperative ptosis after cataract surgery. Other factors like anesthesia and devices are more likely causes.

Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Oculoplastics

Background:

  • Postoperative ptosis is a potential complication following cataract surgery.
  • The role of the superior rectus bridle suture in its development is unclear.

Purpose of the Study:

  • To evaluate the influence of the superior rectus bridle suture on the incidence of post-cataract blepharoptosis.
  • To compare ptosis rates between temporal and superior surgical approaches.

Main Methods:

  • A comparative study of 70 patients undergoing cataract extraction.
  • Group 1 (32 patients): Temporal corneal approach without a bridle suture.
  • Group 2 (38 patients): Superior approach with a bridle suture. Phacoemulsification, peribulbar anesthesia, a pressure-lowering device, and a speculum were used in both groups. Lid position was assessed 12 weeks post-surgery.

Main Results:

  • Postoperative ptosis (≥2 mm) occurred in 11.5% of the temporal approach group and 12.9% of the superior approach group.
  • The difference in ptosis incidence between the two groups was not statistically significant (p > 0.05).

Conclusions:

  • Neither the presence/absence of the superior rectus bridle suture nor the ocular wound site significantly affects postoperative ptosis incidence.
  • Peribulbar anesthesia, pressure-lowering devices, and speculum use are suggested as potential causative factors for ptosis.
