If you’ve never worn contact lenses before, it can seem a bit intimidating. After all, you’re inserting something into your eye! Let’s ease your mind about the first step – your contact lens exam. This post will walk you through what’s involved in a contact lens exam and what you can expect every step of the way.
Scleral contact lenses get their name from the fact that, unlike regular contacts, they vault over the entire corneal surface and rest on the white part of the eye, which is called the sclera. This makes them larger than standard contacts, which in turn provides a variety of benefits. Their size makes them easier to handle and more stable when on the eye, which in turn provides the patient with sharper and more reliable vision. They are also less likely to become dislodged and come out. Dr. McKinnis is a diplomate in Cornea, Contact Lens and Refractive Technologies of the American Academy of Optometry. He is happy to help meet any scleral lens needs you may have in office.
Many patients come to us every day struggling to get through their daily lives with their current choice of vision correction. Some have eyeglasses that do not sit properly on their face or feel that their peripheral vision is hindered by the frames. While contact users may find the lenses uncomfortable or have them fall out at inconvenient times. For these patients, we are pleased to offer orthokeratology, or Ortho-K, a revolutionary way to help you see clearly throughout the day without having to wear glasses or contacts and without having to get laser eye surgery.
Custom Soft Contact Lenses – Soft contacts are generally more comfortable to wear than gas permeable lenses. Recently, some contact companies have been able to create a contact specifically to correct the issues related to mild and moderate cases of keratoconus.
Gas Permeable Contact Lenses – Gas permeable lenses are hard contact lenses that physically forces the eye to adhere to the lens shape. This allows for the correction of keratoconus. The fit is often time-consuming and may take several different lenses to achieve the proper fit.
Piggybacking Contact Lenses – This method is used for individuals who require a gas permeable lens but cannot tolerate wearing rigid contacts. Piggybacking utilizes a soft lens placed on the eye first, and then a gas permeable lens is placed over the top. This offers the comfort of soft contacts with the rigidity and clarity of the gas permeable lenses.
Hybrid Contact Lenses – Hybrid contact lenses were designed specifically for keratoconus. This technology blends a rigid contact lens center with a softer edge, or skirt, of the contact
Scleral and Semi-Scleral lenses – These lenses are gas permeable lenses but cover a larger area of the eye than a standard rigid lens. These lenses don’t put pressure onto the cone shape of the eye. The reduced pressure results in a more comfortable fit for patients.
