The effect of phacoemulsification on corneal endothelial cell density
Archives of Ophthalmology (Chicago, Ill. : 1960)
|March 1, 1978
Summary
Phacoemulsification cataract surgery caused a 33.8% decrease in endothelial cell density (ECD), while intracapsular extraction caused a 14.9% decrease. Phacoemulsification appears more damaging to the corneal endothelium.
Area of Science:
- Ophthalmology
- Corneal Science
- Surgical Outcomes
Background:
- Cataract surgery is a common procedure to restore vision.
- Maintaining corneal endothelial health is crucial for ocular clarity and function.
- Different cataract extraction techniques may impact the corneal endothelium differently.
Purpose of the Study:
- To compare the effect of phacoemulsification versus intracapsular cataract extraction on corneal endothelial cell density (ECD).
- To quantify the endothelial cell loss following each surgical method.
Main Methods:
- Specular microscopy was used to measure ECD in 76 patients post-unilateral phacoemulsification and 10 patients post-unilateral intracapsular cataract extraction.
- The operated eye's ECD was compared to the unoperated contralateral eye.
Main Results:
- Phacoemulsification resulted in a mean ECD decrease of 33.8% compared to the contralateral eye.
- Intracapsular cataract extraction resulted in a mean ECD decrease of 14.9%.
Conclusions:
- Phacoemulsification cataract surgery appears to be more traumatic to the corneal endothelium than intracapsular cataract extraction.
- Endothelial cell loss is a significant consideration in choosing cataract extraction techniques.
