Deep tunnel scleral pocket incisions were developed to control surgically induced astigmatism following cataract and intraocular lens implantation surgery. A more superficial, shallow scleral pocket incision was developed to reduce the rate of postoperative hyphema. To test its effectiveness, a randomized prospective clinical study was performed. One hundred twenty-nine eyes of 129 patients were randomized: 66 to receive a deep tunnel pocket and 63 to receive the superficial pocket. In both groups the incision was made 3 mm posterior to the limbus. For the deep pocket cases, a blade setting of 0.27 mm was used and the wound was dissected forward toward the entry site, creating a long, deep, narrow tunnel. For the superficial wound cases, a 0.17 mm blade setting was used and the entire wound was dissected to the edge of the anatomic limbus, creating a thin scleral flap. The left side was then fanned out toward the left with the entry site slightly into clear cornea. At one day after surgery, 22 cases (34%) in the deep pocket group and four cases (6%) in the superficial pocket group had hyphemas. The difference in hyphema rates was statistically significant (P less than .001).

Ninety patients who had phacoemulsification and implantation of a flexible polyHEMA intraocular lens (IOGEL 1103) were assigned to three groups. After evacuation of sodium hyaluronate retrolentally from the capsular bag, 0.5 ml of 1% acetylcholine chloride, 0.01% carbachol, or balanced salt solution was instilled into the anterior chamber following wound closure. Intraocular pressure (IOP) was measured the day before, and six hours, 18 hours, and one week postoperatively. No topical or systemic antiglaucomatous drug was given during the study period. Preoperatively and one week postoperatively there was no significant difference between the three groups (P greater than .01). At six hours postoperatively the mean IOP decreased in the carbachol group (-2.8 mm Hg) and increased in the acetylcholine and control groups (+0.6 mm Hg and +/- 4.7 mm Hg) when compared with baseline pressures. At 18 hours the mean change from baseline was -3.0 mm Hg in the carbachol group, +0.8 mm Hg in the acetylcholine group, and +2.3 mm Hg in the control group. At six hours IOP exceeding 22 mm Hg was observed in ten of the control patients (30%) receiving balanced salt solution intracamerally and four of the acetylcholine patients (13.3%) but none of the carbachol patients. At 18 hours IOP remained above 22 mm Hg in three of the acetylcholine patients (10%) and four of the control patients (13.3%). Only one of the carbachol patients developed an increase of IOP up to 26 mm Hg at 18 hours. Removal of viscoelastic substances from behind the IOL reduced the incidence of pressure spikes in the early postoperative period.(ABSTRACT TRUNCATED AT 250 WORDS)

A group of 40 postoperative cataract patients had Miller-Nadler glare testing performed before and after midpupillary pharmacologic dilation. The results indicated that pupillary enlargement is associated with increased glare disability. For that reason it is essential to maintain normal pupil shape and function after cataract surgery, a difficult task in cases with miotic pupils.

In this technique, I/A of cortex as a separate step can be omitted, thereby eliminating that portion of the surgical procedure in which posterior capsular disruption most frequently occurs. Residual cortical cleanup is accomplished in the presence of a posterior chamber IOL which protects the poserior capsule by holding it remote from the aspiration port.

A one-handed variation of Gimbel's "divide and conquer" phacoemulsification technique is described. Instead of bimanual cracking, the lens sections are cut, rotated, cut, and removed in sequence.

A surgical method for managing poorly dilating pupils preoperatively is presented. A fine polypropylene suture is preplaced through the inferior iris sphincter prior to an inferior radial iridotomy in preparation for nucleus fracture endolenticular phacoemulsification. Placing the suture prior to the iridotomy assures proper aesthetic and functional alignment of the incised iris pillars, while enlarging the pupil inferiorly accommodates in-the-bag nucleus emulsification. This new surgical method maintains pupillary appearance and function postoperatively.

A new method for enlarging a small pupil during cataract extraction is described. The technique is simple and safe, and uses new instruments that reduce or entirely eliminate the need to incise or suture the iris. This method of pupil enlargement can be used for extracapsular cataract extraction and phacoemulsification procedures.

A 56-year-old woman with tyrosinase-negative oculocutaneous albinism complained of gradually decreasing vision in the left eye. Her visual acuity was 20/300 in the right eye and hand motion in the left eye. She had pink skin and white hair and cilia. On examination, bilateral hypopigmented irides, an opaque lens in the left eye, a hypopigmented fundus in the right eye, and nystagmus were found. An extra-capsular cataract extraction with posterior chamber intraocular lens (IOL) implantation was performed. After retrobulbar anesthesia was administered, the nystagmus ceased temporarily. Postoperatively, visual acuity in the left eye improved to 20/200. We believe IOL implantation is useful in the treatment of cataracts in albino patients.

A 51-year-old man with ankylosing spondylitis had intracapsular cataract extraction and anterior chamber lens implantation in the left eye in 1985. He had localized sclerokeratitis around the corneal section and a protracted anterior uveitis in the immediate postoperative period. He developed a spontaneous extrusion of the implant in 1991 (six years later). The extrusion was through a site 1.5 mm posterior to the previous surgical section. There was no corneal decompensation or corneal melt and no history of trauma. Signs of localized scleritis were present. It is suggested that anterior chamber lens implantation should be avoided under these circumstances.
