Intraocular lens implantation through 3.2 versus 4.0 mm incisions.
OBJECTIVE
To prospectively compare the clinical results of two small incision cataract surgery procedures: silicone intraocular lens (IOL) implantation through a 3.2 mm incision and poly(methyl methacrylate) IOL implantation through a 4.0 mm cruciate incision.


METHODS
Department of Ophthalmology, Ramón y Cajal Hospital, Madrid, Spain.


METHODS
One hundred twenty eyes with cataract were randomly assigned to either procedure. Except for incision width, identical surgical methods were used in every case. Data on uncorrected visual acuity, keratometry, and postoperative astigmatism were analyzed up to 6 months after surgery.


RESULTS
Both groups had similar uncorrected visual acuities. Mean postoperative corneal astigmatism was against the rule with both techniques, and it remained stable during the study. No significant differences between groups were found (P > .1).


CONCLUSIONS
Both procedures offered satisfactory clinical results and were associated with postoperative against-the-rule astigmatism despite the use of the nylon suture.
