Rigid gas-permeable lens problem solving.

Abstract

The introduction of high oxygen-permeable rigid lenses for daily wear has provided practitioners with an excellent alternative to other available lens materials. However, compromise in material properties may, in fact, result in lens-induced complications. This paper describes eight such "typical" problems including a treatment plan and possible alternative methods of treatment. A comprehensive summary table is provided for reference use by practitioners.

[Failures, complications and side effects of radial keratotomy].

The authors present the 10-years results of radial keratotomy in the light of the world literature. The refractive and functional efficacy of this procedure as well as intraoperative and postoperative complications are discussed. The problem of the influence of the radial keratotomy on the endothelium is presented in the light of clinical and experimental investigations. The daily fluctuation of the refraction has been discussed in the aspect of diurnal variations of the intraocular pressure and the changes in corneal thickness resulting from its hydratation. The problem of binocular vision in conditions of postoperative anisometropia is also presented.

Contact Lenses, Extended-Wear

Extended-wear contact lenses: a philosophy for fitting and management.

The fitting and management of extended-wear contact lenses requires a conservative philosophy of patient selection and a structured program of care. Because of the increased risk of serious complications, informed consent must be obtained before fitting patients with lenses. Fitting philosophies favor hydrogel lenses of medium thickness and water content that provide adequate movement. Initial lens care is best provided by peroxide care systems. Patients are usually fitted in the morning, reevaluated in the afternoon, and allowed to wear lenses overnight if there are no contraindications. After reexamination the next morning, planned follow-up is usually provided at 3 days, 1 week, 1 month, and 3 months. If no adverse findings are encountered, patients are seen at 3- to 6-month intervals thereafter.
