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.
