Summary

A continuous circular capsulorhexis preserves anterior capsule integrity during corneal transplants. This technique enables stable intraocular lens placement and reduces risks of tears and decentration.

Area of Science:

  • Ophthalmology
  • Surgical Techniques

Background:

  • Maintaining anterior capsule integrity is crucial for successful cataract surgery.
  • Combined procedures like corneal transplantation and cataract extraction present unique surgical challenges.

Purpose of the Study:

  • To describe a technique combining capsulorhexis with phacoemulsification for combined cataract extraction and corneal transplantation.
  • To highlight the benefits of this approach for intraocular lens stability and capsular integrity.

Main Methods:

  • Performing a continuous circular capsulorhexis.
  • Utilizing phacoemulsification to remove the cataractous lens in fragments.
  • Combining these steps with corneal transplantation.

Main Results:

  • The described technique successfully maintained anterior capsular integrity.
  • Stable "in-the-bag" placement of posterior chamber intraocular lenses (PC-IOLs) was achieved.
  • The risk of radial anterior capsular tears and PC-IOL decentration was minimized.

Conclusions:

  • Continuous circular capsulorhexis combined with phacoemulsification is a safe and effective method for combined cataract extraction and corneal transplantation.
  • This technique enhances the stability of PC-IOLs and preserves the anterior capsule.
  • It offers a valuable approach to minimize complications in complex ophthalmic surgeries.
