摘要:

The variety of causative factors in childhood cataracts, ranging from dominant inheritance to basketball-related trauma, requires great flexibility on the part of the surgeon and many options for surgical approaches and rehabilitative modalities. The search for specific genetic errors that result in cataract may eventually lead to curative gene therapy, but probably not in the near future. For now, trauma prevention, including protective eye wear for sports enthusiasts, and improvements in surgical techniques that reduce postoperative complications offer more immediate benefits. Some increase in acceptance of intraocular lens implantation in children may provide data for long-term effects of the presence of these foreign bodies in human eyes. Contact lenses are generally believed to be the best option for visual rehabilitation, with epikeratophakia and intraocular lenses reserved for selected cases. Visual results in children with associated ocular or systemic disorders remain poor, and solutions to their problems await future research.

摘要:

Posterior capsular opacification after extracapsular cataract extraction is usually caused by a proliferation of lens epithelial cells. This complication may be reduced by atraumatic surgery, thorough cortical cleanup, and use of specific intraocular lens designs. One-piece, biconvex-optic intraocular lenses implanted in the capsular bag seem to form a barrier against central migration of epithelial cells. Various pharmacologic and immunologic methods are being investigated, but long-term clinical data are not yet available.

摘要:

Cataract surgery remains an extremely successful procedure with a very low rate of complications. The advances in surgical techniques and implant varieties have greatly altered the nature and occurrence of complications. As an example, implant dislocations were common a decade ago but are a rarity today. The sophistication of surgery and of manufacturing have resulted in a reduced likelihood for untoward effects of cataract removal and lens implantation. Presently occurring complications are categorized according to the symptoms.

摘要:

We review new findings on the development of glaucoma following pediatric cataract surgery. Other recent findings, concerning inherited syndromes exhibiting cataract and glaucoma, the pseudoexfoliation syndrome, Fuchs' heterochromic iridocyclitis, and lens-induced glaucoma, are commented on. We discuss works on intraocular pressure elevations and secondary glaucoma following routine cataract surgery and neodymium:yttrium-aluminum-garnet laser capsu-lotomy. The past year's studies of combined cataract and glaucoma filtering surgery are also reviewed, including small-incision technique results using foldable implants (phacotrabeculectomy) and preliminary results of using 5-fluorouracil as an adjunct to the combined procedure.

摘要:

Corneal topography analysis has become an indispensable tool in the evaluation and treatment of corneal disease. It is helping us understand the normal corneal shape and how it is altered in ectatic diseases, by contact lens wear, and by surgery. Topography analysis is also now being used in planning procedures to correct astigmatism and in the fitting of contact lenses.
