Phaoemulsification with a 2.75-mm incision resulted in visual outcomes comparable to phaco with a 2.2-mm incision, according to a study published in Optometry and Vision Science.
Jain and colleagues conducted a randomized, prospective comparative study of 50 eyes of 50 patients with senile cataract and less than 1.00 D of astigmatism.
Participants were divided into two groups: 25 patients underwent phacoemulsification with a 2.2-mm clear corneal incision and the other 25 patients underwent phacoemulsification with a 2.75-mm incision.
Researchers measured keratometry, keratometric cylinder, visual acuity, contrast sensitivity and surgically induced astigmatism (SIA) 1 day, 1 week, 1 month, 3 months and 6 months after the procedure.
Results showed that no significant differences were found when comparing the two groups throughout the follow-up period.
The authors explained that developing countries are still searching for a cataract procedure that is effective.
"Microincision cataract surgery, especially with sub-1.8-mm clear corneal incision, may not be feasible for such resource-strained countries," they wrote. "Thus, small-incision cataract surgery (2.75 mm) by phacoemulsification can be regarded as the procedure of choice. Although it has been established that, with shorter incision lengths, SIA can be minimized, there is not sufficient evidence at present to conclusively suggest that results with microincision surgery are superior to those with small-incision surgery." – by Chelsea Frajerman Pardes
