TL;DR: Of the 526 subjects who were treated with the laser, 87.8% had improved vision, with 82.9% achieving a visual acuity of 20/40 or better, which compares favorably with results for the surgically treated population, in which only 68.4% experienced improved vision.

TL;DR: Evidence is provided that indicates long-term alteration of polypropylene may occur, and a continuing search and trial of other plastics to discover an equivalent or even more efficacious haptic material seems desirable.

TL;DR: Axial length measurements obtained by the two methods were highly reproducible and shorter than measurements obtained with the immersion technique by an average of 0.24 mm.

TL;DR: A technique for freeing the nucleus in extracapsular cataract surgery that uses simple cannulas and balanced salt solution in a closed anterior chamber, produces no zonular stress, requires no assistant, needs no iris or capsule manipulation, and is compatible with all methods of nucleus removal including phacoemulsification.

TL;DR: Direct measurement of the capsular bag was performed after extracapsular cataract extraction on 49 cadaver eyes and these lenses had a collapsed bag size of 10.32 +/- 0.42 mm.

TL;DR: A modulated picosecond Nd:YAG laser was used to perform preoperative anterior capsulotomies and posterior capsulaotomies in eyes with and without an intraocular lens, and to cut a variety of cyclitic membranes, iridocapsular adhesions, and vitreous traction bands in more than 6,500 cases.

TL;DR: It is important for all ophthalmologists to be aware of this syndrome in evaluating patients with posterior chamber lenses who present with a transient obscuration of vision and to estimate the overall incidence of transillumination defects to be between 5% and 15%.

TL;DR: A retrospective study of the postoperative use of glasses in 100 patients with bilateral posterior chamber implants found that 11% of patients wore glasses out of habit, even though their visual acuities were equivalent to those of the 14% who subjectively needed no correction after surgery.

TL;DR: Fibrous tissue, uveal tissue, and inflammatory debris were noted on the loops, forming dense synechias at the points of contact with the angle recess, and the edges of the optics were sharp.

TL;DR: Soft hydrophilic intraocular lenses made of an aminopolyamide and a hydroxyethylmethylmethacrylate hydrogel polymer were implanted in cats and followed for six weeks and observation of corneal microvilli may indicate a mild adverse reaction to the hydrogels, possibly from impurities.

TL;DR: The most common adverse finding was an increase in intraocular pressure, which occurred to some degree in 63% of patients, and no statistically significant difference in visual outcome was detected in relation to the time interval between surgery and Nd:YAG laser treatment.

TL;DR: Few of the complications observed at five years are implant-related; macular degeneration is the primary condition causing vision worse than 20/40, and no macular edema and few corneal problems were observed atFive years.

TL;DR: Corneal endothelial cell loss and other complications were analyzed in a series of 344 consecutive extracapsular cataract extraction patients operated on during one year, finding no significant difference between these two groups.

TL;DR: The study indicated that in-the-bag implantation without on- the-table capsulotomy was a safe procedure; anterior-chamber-angle-fixated lenses exhibited a higher incidence of diabetic changes in the anterior and posterior segments than the other lenses.

TL;DR: The IOP in all treated and untreated patients with ocular hypertension on the first day following surgery returned to normal within three days and timolol, therefore, had no effect on acute postoperative pressure elevation following ECCE and posterior chamber lens implantation.

TL;DR: The posterior capsule served as a barrier to large nonelectrolytes or negative electrolytes other than trypan blue, but it did not impede epinephrine, ultraviolet or visible light.

TL;DR: In vitro studies show that axial lengths can be accurately measured by ultrasound after IOL implantation if the different propagation speeds are considered for calculation, and in vivo the retina's curvature counterbalances this apparent increase.

TL;DR: The 91Z had a low incidence of operative complications, good long-term visual acuities, and few short-term complications, but had a high incidence of late, severe, inflammatory/hemorrhagic complications including uveitis-glaucoma-hyphema plus vitreous hemorrhage (UGH+ syndrome), cystoid macular edema, and iris chafing/bleeding.

TL;DR: A technique for repositioning and suture fixation of a subluxated posterior chamber lens via a transiridectomy stab wound is described.

TL;DR: A clinical surgical study of extracapsular extraction/phacoemulsification and lens implantation found little change in the amount of preexistent astigmatism with posteriorlyplaced wounds, but the change was much greater with anteriorly placed wounds.

TL;DR: A case of intraocular lens implantation with an unexpected postoperative increase in spectacle astigmatism but no change in cornealAstigmatism is reported.

TL;DR: Two percent methylcellulose was safe in both the cat and monkey models and facilitated surgery in both models and reduced the endothelial cell loss in the cat eye.

TL;DR: To protect the corneal endothelium from ultrasound damage, phacoemulsification under the anterior capsule was performed on 26 eyes of 21 patients between January 7, 1980, and September 1, 1980 and the best postoperative visual acuity was 20/40 or better in all patients.

TL;DR: Five patients having UGH+ syndrome (uveitis-glaucoma-hyphema plus vitreous hemorrhage) with the IOLAB 91Z intraocular lens (IOL) requiring removal are reported, with one case having significant intraoperative complications.

TL;DR: A lathe-cut intraocular lens was hit with the mode-locked YAG laser and the resulting marks (dinks) were examined with scanning electron microscopy and are described.

TL;DR: The problems associated with intraocular lens (IOL) implantation in two patients with megalophthalmic eyes are discussed and an iris-supported IOL appears to be a satisfactory pseudophakic alternative for anterior megalophile eyes.

TL;DR: The chemical composition and molecular weight distribution of typical materials used for fabrication of intraocular lenses have been determined by high performance liquid chromatography and on-line electronic and FT-IR spectroscopic analysis and the leaching rate of unreacted monomers was determined by Soxhlet extraction techniques.

TL;DR: The results of 100 cases of flexible anterior chamber lens (Stableflex) implantation following intracapsular cataract extraction are reported, with ninety-six percent of patients attained a visual acuity of 20/40 or better.
