Exploring the sting.

Stinging on insertion has been reported by hydrogel lens wearers after use of the AOsept system. The authors investigated the pH of AOsept and various salines used in conjunction with AOsept to determine if there were differences. A significant range (6.57-7.25) was found in the various solutions. The authors recommend the use of a sterile buffered saline as a morning soak for patients using the AOsept system.

Monovision vs. aspheric bifocal contact lenses: a crossover study.

Twenty selected presbyopic patients were fitted with both monovision correction and Hydrocurve bifocal contact lens correction in a crossover study. Eighty percent of the population preferred bifocal correction and 20% preferred monovision. The results suggest that bifocal contact lens correction should be explored prior to considering monovision correction.

Selecting an appropriate hydrogel lens care system.

The selection of the appropriate hydrogel lens care system must incorporate an understanding of the properties and actions of cleaning, disinfecting and rinsing solutions; the characteristics of the lens; and the ocular characteristics of the patient. When changes in a care system are required, reselection involves recognizing: the nature of adverse ocular responses; the nature of deposits; any changes in patient characteristics; the characteristics of potential new products. These factors are considered and used to create an approach to selecting the initial care system and to reselecting an alternate care system.

Disposable contact lenses vs. contact lens maintenance for extended wear.

We compared a disposable extended wear contact lens modality with conventional extended wear over a 6-week period. To do so, we refit 31 patients who had successfully worn conventional extended wear contact lenses for more than 1 year. One eye was fit with the AcuvueR disposable contact lens, and a new extended wear lens of the type the patient had been wearing was placed on the other eye. At weekly intervals the disposable lens was discarded and a new disposable lens inserted. At the same time, the conventional lens on the fellow eye was cleaned, disinfected, and reinserted. After 6 weeks the ocular response, subjective impressions, and condition of the lenses in the two eyes were compared. Both lenses were then cultured. Three subjects had to discontinue disposable lens wear because of adverse reactions to trapped cellular debris and corneal microcysts. Although the results were not statistically significant, the Acuvue lens appeared to perform better than or equal to the conventional lens in biomicroscopic observation, visual acuity measurement, and subjective patient preference. Eighty-seven percent of patients preferred to continue with the disposable system. There were no differences found in the type or degree of microbial contamination of the lenses.
