Retained lens fragments after phacoemulsification can be managed with pars plana vitrectomy, achieving good visual outcomes regardless of timing. Early vitrectomy on the same day as cataract surgery generally led to favorable results.

Area of Science:

  • Ophthalmology
  • Surgical Outcomes
  • Retinal Surgery

Background:

  • Phacoemulsification can lead to retained lens fragments, necessitating further intervention.
  • Pars plana vitrectomy is a common surgical approach for managing such complications.

Purpose of the Study:

  • To analyze the clinical features of patients with retained lens fragments post-phacoemulsification.
  • To evaluate the visual outcomes following pars plana vitrectomy for retained lens fragments.

Main Methods:

  • Retrospective chart review of 62 patients undergoing surgical management for retained lens fragments.
  • Analysis of clinical features, intraocular pressure, corneal edema, and visual acuity.
  • Comparison of outcomes based on timing of vitrectomy and type of intraocular lens (IOL) implanted.

Main Results:

  • Marked intraocular inflammation, elevated intraocular pressure, and corneal edema were common initial features.
  • 68% of patients achieved a final visual acuity of 20/40 or better after vitrectomy.
  • No statistically significant difference in visual acuity was observed based on the timing of vitrectomy (within 7 days, 1-4 weeks, or after 4 weeks).
  • Early vitrectomy (same day as cataract surgery) yielded favorable visual acuity outcomes (20/30 or better in 6/8 patients).

Conclusions:

  • The timing of pars plana vitrectomy does not significantly impact visual acuity outcomes for retained lens fragments.
  • Primary implantation of posterior chamber intraocular lenses (PC IOLs) or anterior chamber intraocular lenses (AC IOLs) did not adversely affect visual outcomes.
  • Same-day vitrectomy is associated with favorable visual acuity and avoids a second surgical procedure.
