Summary

Photic retinal injuries from operating microscopes during cataract surgery occurred in 28% of patients, a rate higher than previously estimated. This highlights a significant risk during intraocular procedures.

Area of Science:

  • Ophthalmology
  • Retinal Surgery
  • Surgical Technology

Background:

  • Photic retinal injuries are a known risk associated with intense surgical illumination.
  • Previous estimates suggested an incidence of less than 10% for these injuries.

Purpose of the Study:

  • To prospectively determine the incidence of photic macular injuries during cataract surgery.
  • To assess the rate of injury from intraocular surgery illumination.

Main Methods:

  • Prospective study of 43 consecutive patients undergoing cataract surgery.
  • Ophthalmic examinations, fundus photography, and oral fluorography were performed pre- and post-surgery.

Main Results:

  • Photic macular injuries developed in 12 of 43 eyes (28%).

  • This incidence is significantly higher than prior estimations.

    • Conclusions:

    • The incidence of photic macular injuries during intraocular surgery is higher than previously reported.
    • Further discussion includes risk factors, cystoid macular edema, and impact on visual acuity.
