Summary

Phacoemulsification safely and effectively removed white cataracts in 212 patients. Visual acuity improved significantly, with a 93.9% success rate at one month, demonstrating its value in developing countries.

Area of Science:

  • Ophthalmology
  • Surgical Techniques

Background:

  • White cataracts present unique surgical challenges.
  • Phacoemulsification is a common cataract removal method.

Purpose of the Study:

  • To evaluate the outcomes of phacoemulsification in eyes with white cataracts.
  • To assess the safety and efficacy of this technique in a developing country setting.

Main Methods:

  • Retrospective analysis of 212 patients with white cataracts (mature, intumescent, hypermature).
  • Phacoemulsification with continuous curvilinear capsulorhexis, nucleus removal via divide and conquer or phaco chop, and intraocular lens implantation.
  • Analysis of pre-operative, intra-operative, and post-operative findings.

Main Results:

  • Low rates of intra-operative complications (e.g., posterior capsular tear 1.9%).
  • Mean phacoemulsification time was 2.03 minutes.
  • Best corrected visual acuity of 6/9 or better achieved in 61.8% post-op day 1 and 93.9% at 1 month.
  • Post-operative complications were generally mild and transient (e.g., striate keratopathy 5.7%).

Conclusions:

  • Phacoemulsification is a safe and effective surgical option for white cataracts.
  • The technique yields favorable visual outcomes in developing countries.
  • Continuous curvilinear capsulorhexis and specific phacoemulsification methods are crucial.
