Summary
Phacoemulsification (Phako) offers superior clinical outcomes for cataract surgery compared to Extracapsular Cataract Extraction (ECCE), with similar costs. Phako results in fewer complications and better visual acuity, making it a cost-effective choice.
Area of Science:
- Ophthalmology
- Surgical Innovation
- Health Economics
Background:
- Cataract extraction is a leading ophthalmic surgical procedure globally.
- Extracapsular cataract extraction (ECCE) was the standard, but phacoemulsification (Phako) is increasingly used due to technological advances.
- Phako requires smaller incisions but involves higher initial equipment costs.
Purpose of the Study:
- To compare the clinical outcomes of phacoemulsification (Phako) versus Extracapsular Cataract Extraction (ECCE).
- To conduct an economic evaluation of both cataract surgery procedures.
- To assess visual acuity, refraction, and complication rates between Phako and ECCE.
Main Methods:
- A two-center randomized trial involving 232 patients receiving ECCE and 244 patients receiving Phako.
- Comparative outcomes included visual acuity, refraction, and complication rates.
- Resource use and costs were monitored across trial and independent centers.
Main Results:
- Phako demonstrated clinical superiority over ECCE.
- Significantly fewer surgical complications and less capsule opacity were observed in the Phako group within one year.
- A higher proportion of patients in the Phako group achieved unaided visual acuity of 6/9 or better, with more stable postoperative astigmatism.
Conclusions:
- Phacoemulsification (Phako) is clinically superior to Extracapsular Cataract Extraction (ECCE).
- Phako is a cost-effective alternative for cataract surgery.
- The overall costs, including postoperative care and spectacles, were comparable, but Phako offered better clinical results.
