Wound architectural analysis of 1.8mm microincision cataract surgery using spectral domain OCT

Micro-incision cataract surgery (MICS) was developed in the last decades to increase the results in phacoemulsi ication surgery. It was derived from the traditional phacoemulsi ication cataract surgery incision called Clear Corneal Incision (CCI). CCI is the global choice technique for cataract surgery procedure, and during years it becomes a safe and effective [1]. The 1.8mm MICS may have some advantage comparing to traditional CCI wound, the advantages includes: reduce the risk for intraoperative anterior chamber instability, less incision bleeding during the surgery, higher structural stability of the anterior chamber, the magnitude of surgically induced astigmatism (SIA), easy in construction and les incidence of postoperative endophthalmitis [2]. Combined with the development of cold phaco technique and intraocular lens for ultra-small incision, greater achievements have been made to improve the cataract surgery quality. However, smaller incisions can produce complications if the incisions are too tight and result in excessive mechanical or thermal corneal trauma [3].
