Area of Science:

  • Ophthalmology
  • Surgical Devices
  • Cataract Surgery

Background:

  • Small pupil size presents challenges during phacoemulsification (cataract removal).
  • Existing iris retractors can be costly or complex.
  • A simple, low-cost alternative is needed for broader accessibility.

Purpose of the Study:

  • To develop and evaluate a self-made disposable flexible iris retractor.
  • To assess its clinical efficacy and safety in small pupil phacoemulsification.
  • To determine its economic and practical value.

Main Methods:

  • A prospective study involving 50 patients undergoing phacoemulsification with the self-made iris retractor.
  • A control group of 50 patients with normal pupil size.
  • Intraoperative data (operation time, ultrasound parameters) and postoperative outcomes (visual acuity, pupil shape, complications, endothelial cell count) were recorded.

Main Results:

  • The self-made retractor successfully expanded pupils to 4.5-5.5 mm.
  • No serious postoperative complications were observed.
  • High rates of good visual acuity recovery (92% at 1 year) and favorable pupil shape were noted.
  • No significant differences in ultrasound parameters or corneal endothelial cell loss compared to the control group.

Conclusions:

  • The self-made disposable flexible iris retractor is safe and effective for small pupil phacoemulsification.
  • It is easily obtainable and demonstrates significant economic and practical advantages.
  • This device is particularly beneficial for primary care hospitals in less developed regions.
