TL;DR: It is proposed that intraocular lenses contaminated with viable bacteria may be implanted into the eye and thereby account for some cases of postoperative uveitis in the pseudophakic eye.
Abstract: One hundred sterile intraocular lenses were placed on the external eye of 50 patients during cataract surgery. Half of the specimens were cultured for bacteria, the other half were examined under the light microscope after fixing and staining. A bacterial contamination rate of 26% was recorded. This is significantly higher than that found in conjunctival swabs (6%) or irrigation specimens (8%) taken at the same time, and higher than that recorded in a group of control lenses (15.2%) exposed to operating theatre air alone. We propose that intraocular lenses contaminated with viable bacteria may be implanted into the eye and thereby account for some cases of postoperative uveitis in the pseudophakic eye.

TL;DR: Patients undergoing elective extracapsular cataract extraction were divided into a control group and treatment group in a double-blinded study to evaluate the nonsteroidal, anti-inflammatory drug flurbiprofen as an aid for maintaining pupil dilation during surgery.
Abstract: Thirty-four patients undergoing elective extracapsular cataract extraction were divided into a control group (18 patients) and treatment group (16 patients) in a double-blinded study to evaluate the nonsteroidal, anti-inflammatory drug flurbiprofen as an aid for maintaining pupil dilation during surgery. Both groups received the routine preoperative dilating drops, and the treatment group also received 0.03% topical flurbiprofen. After lens extraction, the change in pupil diameter from the preoperative measurement averaged -2.5 mm in the treatment group and -3.9 mm in the control group. The difference between groups was significant (p = 0.003), favoring flurbiprofen for maintaining pupil dilation.

TL;DR: Visual acuity declined frequently in both groups, and progression of cataract was the most common cause, and loss of visual acuity occurred much more frequently in patients who were older than 60 years than in younger patients.
Abstract: • Thirty-seven eyes with open-angle glaucoma were treated by trabeculectomy and 34 eyes were treated by thermosclerostomy. Thermosclerostomy lowered intraocular pressure to a slightly greater extent than trabeculectomy; however, the average difference was not statistically significant except for the second year. After five years, IOPs were less than 22 mm Hg without additional medications or surgery in 24 (65%) of eyes undergoing trabeculectomy and in 14 (41%) of eyes undergoing thermosclerostomy. When eyes were included that were treated with medication or additional glaucoma or cataract surgery, over 90% of eyes in each group had an IOP less than 22 mm Hg. Visual acuity declined frequently in both groups, and progression of cataract was the most common cause. Loss of visual acuity occurred much more frequently in patients who were older than 60 years than in younger patients.

TL;DR: Data from the small group of patients who underwent surgery in which the technique of phacoemulsification was used show that the smaller changes in corneal curvature are attributable to the smaller incision size and reduced number of sutures.
Abstract: The changes in corneal curvature were determined at regular intervals over a one-year period following intracapsular cataract extraction by microsurgical techniques. During the first postoperative month photokeratometric measurements showed rapid changes in astigmatism associated with large changes in the direction of the axis. Thereafter astigmatism against-the-rule predominated. Data from the small group of patients who underwent surgery in which the technique of phacoemulsification was used show that the smaller changes in corneal curvature are attributable to the smaller incision size and reduced number of sutures. With patients who underwent intracapsular extraction a comparison has been made between the effects of large and small section sizes, and a procedure is outlined whereby surgically induced astigmatism may be minimised.

TL;DR: It is concluded that many of the problems associated with ICCE and iris-supported lens implantation seem to be eliminated with the ECCE-posterior chamber IOL procedure, however, it is emphasized that careful longterm follow-up is required to determine safety.

TL;DR: It is concluded that the shape of the vernier threshold-versus-gap function is a good indicator of the functional severity of the cataract in patients with otherwise normal vision.
Abstract: The resistance of certain types of hyperacuity tasks (eg, vernier acuity) to optical degradation of the retinal image has been demonstrated previously. This suggests that such a task might provide a means of filling the clinical need for a reliable test of retinal function in the presence of cataracts and other ocular opacities. In the present study, we measure several aspects of vernier acuity performance in cataract patients. These data provide an early basis for the development of a vernier acuity test to detect retinal/neural visual loss prior to cataract surgery. We report the results of measurements in 15 cataract patients using a two-dot vernier acuity task with variable separation between the two dots (gap). The data indicate that the shape and mean level of the vernier threshold-versus-gap function co-vary with the functional severity of the opacity as corroborated by Snellen acuity measures. Furthermore, the optical effects of the cataracts we studied are very similar to the effects of degrading the visual stimulus by interposing ground glass for a normal observer. We conclude that the shape of the vernier threshold-versus-gap function is a good indicator of the functional severity of the cataract in patients with otherwise normal vision.
TL;DR: Regular follow-up of all children with anterior cataracts is recommended until a secure assessment of vision can be made, as early ophthalmological examination did not always allow us to forecast later visual disability.

TL;DR: One hundred six consecutive patients undergoing elective cataract surgery were divided into a control group and treatment group in a double-blinded study to evaluate the non-steroidal, anti-inflammatory drug indomethacin as an aid for maintaining pupil dilation during surgery.
Abstract: One hundred six consecutive patients undergoing elective cataract surgery were divided into a control group and treatment group in a double-blinded study to evaluate the non-steroidal, anti-inflammatory drug indomethacin as an aid for maintaining pupil dilation during surgery. Both groups received the routine preoperative dilating drops, and the treatment group also received 1% indomethacin. After lens extraction, the change in pupil diameter from the preoperative measurement averaged 0.27 mm in the treatment group and 0.84 mm in the control group. The difference in control groups was significant (p = 0.001), favoring indomethacin for maintaining pupil dilation.

TL;DR: A two-part study to determine whether any positive association between the use of allopurinol and the development of cataracts could be demonstrated was demonstrated.
TL;DR: Orally-administered fluorescein was used as a quantitative test of the blood-aqueous barrier in a group of patients who had undergone cataract extraction and intraocular lens implantation in one eye.
TL;DR: There was no significant difference between cases performed with and cases performed without the Terry keratometer at various postoperative gates, and the lack of difference is due to biological variables which affect intraoperative readings and postoperative wound healing.
TL;DR: In this article, the indications and risks of iridectomy with cataract surgery are discussed and four case reports are presented, including three cases where the iris was not performed and a pupillary block developed.

TL;DR: Use of IOLs appears to have contributed to changing indications for cataract surgery among some ophthalmologists, and a larger, more comprehensive study would be needed to determine the full extent of these trends.
Abstract: Despite the fact that two community-based surgeons switched from routine intracapsular cataract extraction to planned extracapsular cataract surgery and routine implantation of posterior chamber lenses, they did not materially increase the size of their surgical load or change their indications for cataract surgery. In contrast a similar change in surgical technique by two high-referral hospital-based surgeons was associated with a marked increase in operative rates and increased preoperative acuity. A significant proportion of this change appeared to represent reduced reluctance toward monocular cataract surgery. By eliminating the aniseikonia of monocular aphakic and visual distortion of aphakic spectacle correction, use of IOLs appears to have contributed to changing indications for cataract surgery among some ophthalmologists. A larger, more comprehensive study would be needed to determine the full extent of these trends.
TL;DR: Results of prospective concurrent trials of IOL implantation performed at the Wilmer Institute are presented, with particular reference to the posterior chamber intraocular lens and with specific emphasis on postoperative complications.
Abstract: Intraocular lens (IOL) implantation is now accepted as the most effective means of aphakic correction in selected patients undergoing cataract surgery. In terms of final rehabilitation, however, complications such as corneal oedema, retinal detachment, and cystoid macular oedema remain problematic. Results of prospective concurrent trials of IOL implantation performed at the Wilmer Institute are presented, with particular reference to the posterior chamber intraocular lens and with specific emphasis on postoperative complications.
TL;DR: An analysis of patient histories and eye findings reveal interesting facts, including the time between cataract surgery and onset of visual decrease was three months, and the presence of systemic vascular disease in the patient does not seem to determine the eye's long term visual performance.
TL;DR: A retrospective analysis of the results of extracapsular cataract surgery with and without implant is presented, finding that aphakic retinal detachment occurred in only one eye and the need for this procedure declines, becoming negligible after 3.5 years.
Abstract: A retrospective analysis of the results of extracapsular cataract surgery with and without implant is presented. Surgery was performed by a group of consultants and registrars from 1975 to 1982, and minimum patient follow-up was 12 months (mean 26.2 months). The incidence of postoperative capsulotomy was 14.3%, but the need for this procedure declines, becoming negligible after 3.5 years. Of 242 eligible eyes, aphakic retinal detachment occurred in only one.

TL;DR: A cloudy, floating opacity was found in a bottle of irrigating solution during routine cataract surgery and this was subsequently identified as Penicillium, and the patient was successfully treated.
Abstract: A cloudy, floating opacity was found in a bottle of irrigating solution during routine cataract surgery. This was subsequently identified as Penicillium, and the patient was successfully treated. Surgeons are urged to check the containers of solutions used for intraocular irrigation prior to beginning surgery.
TL;DR: All patients undergoing cataract surgery in which the use of intraocular acetylcholine is contemplated should be monitored by an anesthesiologist, although a cause-and-effect relationship has not been proven.
TL;DR: It is shown that iris leakage is a common feature of cataract surgery in the immediate postoperative period and the type of extraction does not influence the appearance of these iris angiographic findings.
