Abstract Details



Purpose:

The objective of this study was to analyze the therapeutic benefits with soft hydrophilic contact lenses in cases of bullous keratopathy due to endothelial pseudophakic decompensation.

Setting:

Universidad Europea de Madrid Centro Adscrito de Valencia

Methods:

25 is the number of patients studied and the CL used was PureVision®Bausch&Lomb, Rb (8.6 mm), Ø (14.00 mm). The CL was strictly used for therapeutic purpose, as a temporary protection. Previously to the fitting of the CL, an eye examination was fully performed to every patient. Once fitted, reviews took place every 24 hr, 7 days, 15 days, 1 month, 3 months and 5 months after using the CL, by means of anterior segment biomicroscopy. The terms of use of the CL was permanent and monthly replacementent. In some cases – when required- artificial tear was used.

Results:

The group consisted of 15 men and 10 women. 19 of these patients experienced a noticeable improvement between the 15 days and a month after the fitting of the lens, because they had little bullae and epithelial alteration. The rest -6 cases with prevailing big and spread bullae all over the cornea- it took at least three months on average to disappear. All the patients improved their photophobia problems as well as an immediate relief regarding the pain after the CL fitting. Similarly, there is an improvement regarding tearing problems.

Conclusions:

Bullous keratopathy is characterized by a failure on the endothelial layer of the cornea. It presents an epithelial and stroma edema with the consequent appearance of bullae or painful chronic blisters. A protective treatment is absolutely necessary as an initial procedure. When a soft hydrophilic lens is fitted, a loss of water by evaporation takes place, leading to a flow of water through the epithelium and it offers to the eyelid edge and palpebral conjunctiva a uniform surface instead of a rough and bumpy cornea. The patients with bullous keratopathy show a significant clinical improvement after the use of soft hydrophilic CL.
