[A comparison of clinical effects between phacoemulsification and intraocular lens implantation through "L-shaped" and 3.2 mm scleral tunnel incision].
OBJECTIVE
To study the implant surgery through a newly designed L-shaped sutureless scleral tunnel incision and compare the therapeutic effects of this incision with the conventional 3.2 mm scleral tunnel incisions.


METHODS
Phacoemulsification was performed through a L-shaped incision with implantation of 6 mm PMMA intraocular lens (IOL) and 3.2 mm scleral tunnel incision with implantation of acrylic foldable IOL. Uncorrected visual acuity and corneal topography were examined before the operation and 1 day, 7 days, 1 month, 3 months after the operation.


RESULTS
From 1 day to 3 months post-operatively, there was no statistical difference between the two groups in uncorrected visual acuity, surgical induced astigmatism and axis of corneal astigmatism. The preoperative and the post-operative corneal topographies of the two groups were similar.


CONCLUSIONS
The therapeutic effects of the two groups are similar. In the L-shaped scleral tunnel incision group, the less expensive PMMA IOL can be used.
