Unlike any other consumer products, the improper use of contact lenses would cause damages to the eyes. Contact lens users are advised to have regular aftercare.
Proper contact lens fitting procedures should involve detailed refraction, examination of corneal health and its curvature, assessment of tear volume and quality. Under certain circumstances, the use of corneal topographer will be needed for in-depth analysis of corneal curvature. Contact lenses with suitable power, material and parameters will be recommended based on these findings.
Contact lens users should have regular aftercare in order to ensure the lenses are still suitable for them. The test would involve examination of corneal and conjunctival health, tear quality, contact lens fitting and prescription.
