Objective: To observe and compare the difference of anterior chamber angle after Phacoemulsification and Intraocular Lens Implantation (Phaco & IOL) through a tunnel incision and Extra Capsule Cataract Extraction and Intraocular Lens Implantation (ECCE & IOL).
Methods: The changes of internal incision, the peripheral iris and the fixation of lens intracapsular of 36 eyes were individually observed after the operation.
Results: Desemet's membrane detachments occurred in three eyes (8.35%) in the group of Phaco & IOL and four eyes (11.1%) in the group of ECCE & IOL. The difference was not significant. (P > 0.05) Peripheral anterior synechiae occured in three eyes (8.35%) of Phaco & IOL group and in 17 eyes (47.27%) of ECCE & IOL group. The difference was significant (P < 0.05). Intracapsular lens account for 31 eyes (86.1%) of Phaco & IOL group and ten eyes (22.5%) in ECCE & IOL group. The difference was statistically significant. (P < 0.05)
Conclusion: Phaco & IOL can decrease the incidence of peripheral iris anterior synechiae and increase the chance of intracapsular placement of IOL.
