Maximal subtotal extirpation of the horizontal rectus extraocular muscles for the treatment of nystagmus with no null point. A report of four successful human cases.

Purpose: To evaluate the visual and restoration of normal appearance results of maximal excision of the horizontal rectus muscles in nystagmus patients.

Setting: Menelik II Hospital, Addis Ababa, Ethiopia and the Sinskey Eye Institute, Santa Monica, California.

Cataract extraction and intraocular lens implantation in an infant with a monocular congenital cataract.

A cataract extraction and primary capsulotomy with intraocular lens (IOL) implantation was performed on a 17-day-old infant with a monocular mature congenital cataract. The IOL power, calculated at the time of surgery, was undercorrected to compensate for the growth of the eyeball. Two additional surgical procedures were required to resolve visual axis obstruction caused by lens epithelial cell proliferation.

Induced astigmatism in a 6.0 mm no-stitch frown incision.

Fifty-five consecutive patients had cataract extraction with a 6 mm no-stitch frown incision and implantation of a 6 mm optic three-piece posterior chamber lens. Vector analysis calculations of diopters (D) of mean induced keratometric astigmatism for this incision were 0.70 D at one day, 0.
