Optometrist in Odessa Talks Hard To Fit Contact Lenses
Traditionally, not every patient is a good candidate for contact lenses. Patients with certain eye conditions make it difficult for optometrists to fit lenses into their eyes to correct their vision. Fortunately, contact lens manufacturers have created a wide variety of specialty lenses for patients who never had a chance to wear them before. At Vision Source Odessa, we're proud to offer contact lenses for hard to fit eyes, giving our patients another great set of options for vision correction.
About Hard to Fit Contacts
Hard to fit prescriptions are needed for any number of eye conditions, most of which make it physically difficult for the patients to wear common contact lenses. Our optometrist in Odessa TX says that it's all about the ability to correct your vision and wear the lenses comfortably all day. Some of the more common hard to fit conditions are:
- Chronic dry eyes
- Post-refractive surgery
Types of Contact Lenses
Each condition poses a different challenge for contact lens manufacturers, with each one having different physical requirements. In our office, patients with astigmatism are often fitted with Toric lenses. They come in both soft and rigid gas permeable varieties. Soft Toric lenses are more common because there is virtually no breaking in period. Finding the right Toric lens fit can be a challenge, and sometimes multiple pairs must be tried before we get the right fit.
If you've got chronic dry eyes, your best solution is a new type of lens that retains a higher percentage of moisture, giving you a more comfortable fit. Rigid gas permeable lenses are another good option, because they don't absorb moisture from the eye like some soft lenses do.
With keratoconus, the cornea of your eye is misshapen. This makes it very difficult to find regular contact lenses that fit smoothly into your eye. We like to use gas permeable lenses for this condition. The lenses allow oxygen to penetrate to your eye, but, being rigid, they don't have to smooth over the surface of your eye. These contact lenses can give you sharper vision than eyeglasses. If the bulge in your eye is too large to fit even gas permeable lenses, we'll offer scleral lenses, which are larger lenses that rest on the whites of the eye.
Many patients over the age of 40 begin to develop presbyopia, the inability to focus on small object close up. If you wear eyeglasses, this is easily corrected with bifocal lenses. We now have bifocal and multifocal contact lenses that do the same job, allowing you to focus on different prescriptions for different parts of your field of vision.
If you've had refractive surgery, you might be wondering why you'd even need contact lenses. Sometimes the surgery doesn't correct your eyes perfectly, and sometimes your vision may worsen after a number of years. Often, a second surgery isn't an option, so contact lenses are needed to correct the vision problems. We offer a wide variety of lenses for these occasions, depending on the degree of correction you need.
Contact Lens Exams
Examinations for contact lenses begin exactly the same as those for eyeglasses. We'll do a check for visual acuity, to find out the prescription needed to correct your vision. Once our optometrist finds out how much correction you need in your eyesight, he'll do a check on your eyes to determine whether there are any signs of eye diseases such as glaucoma or cataracts. This examination will usually show any signs that hard to fit contact lenses will be needed.
Once the optometrist knows the condition of your eyes, he'll measure your eyeball's size and curvature. This ensures that your lenses will perfectly fit your eyes in a comfortable manner.
