Purpose: To study the compliance of contact lens (CL) wearers and the prevalence of CL-related ocular complications. Materials and Methods: This was a cross-sectional study conducted from December 2012 to May 2013 which included CL wearers coming to outpatient department or emergency department where these patients underwent ophthalmic examination. An interview was performed about the use and care of CLs. Results: The study included 102 patients, where 26 (25.50%) were men and 76 (74.50%) were women. Patient's ages ranged from 13 to 55 with an average (mean ± standard deviation) 29.48 years. Results showed myopia in 41 (40.19%), hyperopia 13 (12.74%), astigmatism 37 (36.27%), keratoconus 8 (7.84%), and others 3 (2.94%). More than 2/3 of the patients had, at least, one complication in their eyes. The average complication rate of gas permeable (GP) lenses was significantly (P < 0.04) lower than soft CLs (SCLs) (0.75). The most common complications were papillae, giant papillary conjunctivitis, conjunctival injection, corneal infiltrates, and corneal abrasions in both GPs and SCLs wearers. Silicone SCLs had a lower average number of complication rates per eye (0.73) than nonsilicone SCLs (0.76), but the difference was not statistically significant (P = 0.19). Extended wear CL use was associated with higher complication rate (86.84%) as compared to daily wear CL use (67.85%) and it was statistically significant (P < 0.03). Conclusion: Use of CL is associated with ocular complications. Most of these complications are minor and easily manageable. It is advised that patients should adhere with the recommendations of both manufacturer and optometrist to avoid complications.
