Contact Lens Fitting
Just like eyeglasses, the primary purpose of contact lenses is to correct common vision problems. Myopia (nearsightedness), hyperopia (farsightedness), astigmatism (blurred vision) and presbyopia (visual problems resulting from aging rigid lenses) are some of the conditions that require the use of visual aid devices. For many, contacts are a preferable alternative to glasses, allowing more freedom than glasses can provide. However, people with Keratoconus (degeneration of the structure of the cornea) are unable to wear typical contact lenses due to an irregular shape of the eye. This asymmetry is caused by a thinning of the cornea that forces the eye to bulge forward and blur vision. For most patients living with Keratoconus, fitted rigid gas-permeable contact lenses are the best solution.
Your First Contact Lens Appointment
The process of fitting rigid gas-permeable contact lenses is a fairly simple two part process. First you will schedule a consultation to make sure fitted contacts are the best way to proceed. If our doctors agree with you, then you will be scheduled for the actual fitting. During the fitting, our doctor first measures your eye’s surface. The measurement taken reflects the ocular surface quality, tear film, the corneal curvature, eye structure and the refractive data necessary to fit the lenses correctly. When everything is complete, our doctor will prescribe the appropriate lens prescriptions and schedule any necessary follow-up visits.
With hard lenses, like the rigid gas-permeable lens, there is a longer adjustment period than with soft contact lenses. You should allow 2 to 4 weeks for your eye to adjust and become completely comfortable. However, once your eye becomes accustomed to the new lens there shouldn’t be any problems. Some RGP lenses can even be worn overnight and as long as a week without changing them.
