In a new surgical procedure, adverse reactions or complications may surface without most ophthalmic surgeons experiencing them or being aware of them. Even those with a large series of cases may never see certain problems. Through a collaborative effort with over 200 radial keratotomy surgeons totaling 63,000 cases nearly every significant complication has been documented. This study of radial keratotomy complications includes the number of patients and percentage of the total of the following: intraoperative occurrences which generally do not affect vision, which include microperforations and macroperforations; postoperative changes which do not affect vision: limbal "peeking" and star pattern with light; transient occurrences which tend to resolve with time: ptosis, recurrent erosions, corneal ulcer, microwound abscess, delayed wound healing, inferior rectus palsy, glare or fluctuating vision after six months, iritis, and stromal keratitis; postoperative changes which can affect vision (correctible): overcorrection more than 1.5 diopters, marked undercorrection more than -2.00 diopters, irregular astigmatism, neovascularization after soft-contact-lens wear, and best-corrected acuity decreased usually only one line; and postoperative changes which can affect vision (uncorrectible): retrobulbar hemorrhage and endophthalmitis, loss of the eye, herpes keratitis, and cataract formation.

A safe effective method of global control during anterior segment surgery is presented. The method used in 1184 consecutive cases was the scleral yoke traction suture adapted from a method often used in strabismus surgery. The incidence of postoperative ptosis severe enough to require surgical correction is presented in that group as well as in a group of 591 consecutive cataract extractions utilizing the classic superior rectus traction surgery. The principle advantages of this method as compared to the classic superior rectus traction suture are pointed out, with emphasis on the reduction of postoperative ptosis.

A new instrument for use in prolapsing a cataract nucleus into the anterior chamber during extracapsular cataract extraction is described. This instrument is a modification of the Kelman Blunt Irrigating Cystatome and the Youens Lens Manipulating Cannula. The tip is elongated, rounded, broadened, and set at an angle from the instrument shaft to enhance broad surface contact of the instrument tip with the nucleus equator. In a recent series of 100 consecutive cataract procedures it was possible to completely prolapse the nucleus into the anterior chamber in all but six cases. The surgical technique is described.

Seven patients with acquired ptosis and normal levator function following anterior radial keratotomy are presented. Five of these patients then elected to undergo radial keratotomy of the opposite eye, and four had symmetrical lid fissures (mild bilateral ptosis) after bilateral surgery. Ptosis is a well-known complication of cataract extraction, but has not been reported following radial keratotomy. Unlike cataract extraction, radial keratotomy does not require anesthetic injections, bridle sutures, or conjunctival flaps. The rigid Knapp eyelid speculum used in these cases remains as the only apparent cause of eyelid trauma and subsequent ptosis. During radial keratotomy, the speculum was opened widely in order to provide good corneal exposure and avoid contact with the diamond knife. Contraction of the orbicularis oculi muscle against the rigid speculum may have traumatized the lid, resulting in a levator aponeurosis disinsertion and subsequent ptosis.

Aponeurotic defects are consistently found in senile ptosis and the ptosis following cataract surgery. Correction by an anterior approach to the levator aponeurosis is satisfactory and has the advantages that excess skin can be excised at the same time and the posterior lid lamella is left intact. Results in 25 patients (36 lids) are reviewed.

A prospective, randomized, double-masked study was conducted to compare the efficacy of steroid/antibiotic treatment to placebo in reducing postoperative ocular inflammation. Patients undergoing planned extracapsular cataract extraction with intraocular lens implantation were treated with either placebo or a combination product containing dexamethasone, neomycin, and polymyxin B for three days prior to surgery and three weeks following surgery. Five of thirteen (38%) patients treated with placebo developed significant iritis postoperatively, while none of ten (0%) patients treated with the combination product developed excessive inflammation (P = 0.027). Two patients treated with the steroid/antibiotic combination product experienced a broken suture postoperatively followed by iris prolapse, as compared to none in the placebo group (P greater than 0.10). More types and significant numbers of bacteria were isolated from the eyes of the placebo-treatment group after therapy than were found in the steroid/antibiotic-treatment group.

The clinical outcome and final visual acuities of 29 patients with intracapsular lens extraction and keratoplasty to 38 patients having extracapsular cataract extraction and keratoplasty were compared. Grafts remained clear in 89% of the intracapsular group and 82% of the extracapsular group over an average follow-up of 38 months and 21 months, respectively. Ninety-one percent of eyes with intracapsular lens extraction and 70% of eyes in the extracapsular group achieved a final visual acuity of 6/21 (20/70) or better. We found a significantly higher incidence of additional surgery in the extracapsular group and glaucoma in intracapsular combined cases. Late vitreous prolapse with vitreo-endothelial membrane formation and graft decompensation was a discouraging complication in three eyes having intracapsular extractions.

6,485 cases of cataract extraction are reviewed. Iris prolapse was a post-operative complication in 32 cases. (Incidence = 0.49 per cent). It is a relatively uncommon complication of present day cataract surgery, and it is postulated that iris prolapse results from transient pupillary block, in the post-operative period.

Cataract surgery after goniotrepanation has been performed on 75 eyes at the St. Demetrius Hospital Eye Clinic in Thessaloniki , Greece, in recent years. The patients' ages ranged from 46 to 84 years. Intraocular pressure was between 8 and 19 mm Hg in all but 4 eyes which had IOPs of between 22 and 30 mm Hg. In order to leave the fistula untouched, the incision with the Graefe knife was made in the area of the cornea close to the limbus; it was closed with 7 sutures (7-0 silk). Prolapse of the vitreous occurred in 7 cases. It was possible to follow up 52 of the eyes: IOP remained regulated postoperatively with one exception (26 mm Hg); the upper pressure limit was 18 mm Hg.

Excellent results are obtainable with well-proved lenses. For those using intracapsular methods, I can give assurance that it is not necessary to change in order to use intraocular lenses safely. The prerequisites are an established safe technique for routine cataract surgery with good visual results. Proper wound closure should be demonstrated by an absence of cases of shallow or absent anterior chamber, of iris prolapse, or postoperative hyphaema. No intraocular lens of any kind should be used unless the quality of routine cataract surgery is high in these respects as well as in avoiding damage to the corneal endothelium. The choice of intraocular lens should be one which can be applied to the surgeon's well-established method and it should also be a well-established lens which has a safe long-term record.
