Extracapsular cataract extraction (ECCE) and phacoemulsification (PHACO) show similar outcomes in vitrectomized eyes. Deep anterior chamber is more common with PHACO after extensive vitreous removal, requiring technique adjustment.

Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Cataract Surgery

Background:

  • Cataract surgery in previously vitrectomized eyes presents unique challenges.
  • Comparing extracapsular cataract extraction (ECCE) and phacoemulsification (PHACO) is crucial for optimizing outcomes.

Purpose of the Study:

  • To evaluate and compare the outcomes of ECCE and PHACO in eyes that have undergone prior vitrectomy.
  • To assess intra-operative and postoperative complications and visual results.

Main Methods:

  • Retrospective study comparing 56 vitrectomized eyes undergoing ECCE with 60 vitrectomized eyes undergoing PHACO.
  • A control group of 65 eyes undergoing PHACO without prior vitrectomy was included.
  • Statistical analysis using Chi-squared, independent samples, and paired samples tests.

Main Results:

  • Deep anterior chamber was significantly more frequent in the PHACO group of vitrectomized eyes, especially after extensive vitreous removal.
  • No significant difference in intra-operative and postoperative complications between ECCE and PHACO in vitrectomized eyes.
  • Vitrectomized eyes showed higher rates of posterior synechiae, posterior capsular opacification (PCO), and retinal detachment (RD) compared to controls.

Conclusions:

  • Phacoemulsification may require technique modification, such as lowering bottle height, in vitrectomized eyes with extensive vitreous removal to prevent deep anterior chamber.
  • ECCE and PHACO demonstrate comparable visual outcomes and complication rates in previously vitrectomized eyes.
  • Vitrectomized eyes are at increased risk for specific intra-operative and postoperative complications, including RD and PCO.
