Summary
Phacoemulsification and planned extracapsular extraction show similar outcomes, but phacoemulsification offers advantages like smaller incisions. Both procedures are effective for cataract removal, with surgeon experience influencing technique choice.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Cataract Surgery
Background:
- Phacoemulsification is increasingly preferred for cataract extraction, yet planned extracapsular extraction remains in use.
- Surgeon experience correlates with a preference for phacoemulsification.
- Anterior capsule opening techniques (capsulorhexis vs. can opener/letter box) and incision sizes vary between the two procedures.
Purpose of the Study:
- To prospectively compare phacoemulsification with planned extracapsular extraction in cataract surgery.
- To evaluate differences in intraoperative parameters and postoperative outcomes between the two techniques.
Main Methods:
- A prospective study comparing 100 consecutive patients undergoing phacoemulsification with 100 undergoing planned extracapsular extraction.
- Measurements included irrigation volume, irrigation duration, endothelial cell loss, and postoperative astigmatism.
Main Results:
- Mean irrigation volume was higher in phacoemulsification (96.6 ml) vs. extracapsular extraction (48.1 ml).
- Endothelial cell loss was comparable (7.9% vs. 7.1%).
- Mean postoperative astigmatism was significantly lower after phacoemulsification (1.0 dpt) compared to extracapsular extraction (3.3 dpt).
Conclusions:
- Phacoemulsification and planned extracapsular extraction yield comparable outcomes, except for lower postoperative astigmatism with phacoemulsification.
- Phacoemulsification offers benefits such as smaller incisions, a closed system, and controlled intraocular pressure.
