Summary

Blunt trauma can cause late wound dehiscence in pseudophakic patients, leading to intraocular lens dislocation or expulsion. Long-term protective eyewear is crucial after cataract surgery to prevent such serious complications.

Area of Science:

  • Ophthalmology
  • Trauma Surgery

Background:

  • Late wound dehiscence following cataract surgery can occur due to blunt trauma.
  • Pseudophakic eyes are susceptible to ocular injuries long after initial implantation.

Purpose of the Study:

  • To investigate the incidence and outcomes of blunt trauma-induced wound dehiscence in pseudophakic patients.
  • To highlight the risk of intraocular lens (IOL) complications and associated ocular injuries.

Main Methods:

  • Retrospective case series of 11 pseudophakic patients (11 eyes) who experienced blunt trauma.
  • Analysis of injury mechanisms, timing of wound rupture, IOL status, and associated ocular pathologies.

Main Results:

  • Wound dehiscence occurred 3 days to 1 year post-surgery, most commonly from falls.

  • Five IOLs dislocated, one fractured, and two were expelled.
  • Iris prolapse occurred in all patients; hyphema in seven, vitreous prolapse in four, and retinal detachment in three.
  • Six patients achieved a visual acuity of 20/40 or better after surgical repair.

    • Conclusions:

    • Limbal wounds in pseudophakic eyes are vulnerable to late dehiscence from blunt trauma, potentially disrupting IOL position.
    • Patients need counseling on the importance of lifelong protective eyewear after cataract surgery with IOL implantation.
