Complications Reported with Hydrogel Extended Wear Contact Lenses

Key Points

Evaluate the incidence of complications associated with extended wear contact lenses.
Conducted a survey with 137 sent out, achieving 44 responses and 15 with usable data.
Analyzed follow-up care ratios between dispensing and follow-up visits.
Assessed incidents of specific complications reported by participants.
Follow-up to dispensing ratio varied significantly, indicating uneven care.
Incidence of epithelial micro-cysts, striae, and giant papillary conjunctivitis lower than previous reports.
Red-eye response and corneal ulcers found at the lower end of previously reported ranges.
Seasonal variation observed in GPC and red-eye incidence, with increases noted in March.

Abstract

ABSTRACT We conducted a survey to evaluate the incidence of various complications associated with extended wear (EW) contact lenses. Of the 137 surveys sent out, 44 responded, 15 with data. The analysis indicates: (1) EW contact lens patients receive nonuniform care, evident from the fact that the EW follow‐up to EW dispensing ratio varied between 1.6 and 16.75; (2) the incidence of epithelial micro‐cysts, striae, and giant papillary conjunctivitis (GPC) was found to be considerably lower than that reported previously; (3) the incidence of “red‐eye” response and corneal ulcers was calculated to be within the lower end of the range of previously reported research; and (4) there may be a seasonal variation in the incidence of GPC and red‐eye response as indicated by an increase in both conditions during the month of March as compared to February.
