To describe the type of complications
related to contact lens
wear seen in a hospital setting in Singapore.
Data were collated over a 2-year period from April 1999 to March 2001, from all public hospitals in Singapore. A standardized clinical record form was completed by the attending doctor when a patient presented for contact lens
Nine hundred and fifty-three contact lens
were recorded. The mean age of presentation was 26.4 years. Women made up the majority n=491 (68%). Most patients were Chinese (555, 77%). Six hundred and seventy-six (93.7%) patients were soft contact lens
wearers. Most patients, 585 patients (85.2%) wore their lenses on a daily basis. Two hundred and forty-four cases (25.6%) of infective keratitis
were seen, with 55 patients requiring hospital admission for management of the infection. Soft disposable contact lens
wear was associated with the majority of the infective keratitis
(178, 73%). Epithelial keratitis
occurred in 229 patients (24.0%) with punctuate epithelial erosions being the commonest presentation in 139 (14.6%). Allergic conjunctivitis occurred in 179 (18.8%) of the cases with giant papillary conjunctivitis accounting for 147 (15.4%) of them. Dry eyes (77, 8.1%), sterile infiltrates (71, 7.5%) and neovascularization of the cornea (75, 7.9%) were the next commonest complications
edema, solution- and lens-related complications
occurred in small numbers, accounting for less than 5% of the complications
secondary to soft lens wear was the most common complication, followed by epithelial keratitis
and allergic conjunctivitis seen in public hospitals in Singapore.
