Eyeglasses can do a great job of correcting common refractive errors such as myopia, hyperopia, presbyopia and astigmatism. However, if you lead an active life, play contact sports or simply don’t want to perch a pair of glasses on your nose all of the time, you will most likely want to get contact lenses. A separate contact lens exam is required to ensure that your contacts fit correctly and comfortably, correct your vision as precisely as possible, and suit your health and lifestyle requirements.
If you’ve recently had a prescription for corrective lenses created or updated, then you may not need a fresh vision exam. You can simply bring that prescription and/or your current pair of glasses to your contact lens exam at Shreveport Eye Clinic. (It’s worth noting that this exam is typically billed separately and is not necessarily covered by your insurance plan.) If it’s been a while since you had your vision tested, we need to evaluate it again to make sure we have a current vision correction prescription before we move forward.
Precise measurements of the cornea, irises and pupils of both eyes must be made in order to produce contact lenses that will fit comfortably without harming the eye and correct refractive errors with optimal precision. Keratometry and corneal topography give us an accurate understanding of your corneal contours, while pupil gauges and other instruments help us collect the other data.
What Type of Contact Lenses are Right for Me?
There are many types of contact lenses available to suit specific correction requirements and lifestyle needs. For example, if you require multifocal eyeglasses due to presbyopia, you’ll need multifocal contact lenses as well. Patients with giant papillary conjunctivitis, an irritation caused by the body’s own proteins, will want contacts that can be replaced frequently such as single-use disposable lenses. People with keratoconus, a cone-like bulging of the corneas, may need scleral lenses that “vault” completely over the corneas.
We will undertake a full eye health examination to determine what kind of contact lenses will do the best job for you. For instance, tear film evaluations can tell us whether your eyes will need some extra help from lenses constructed of moisture-retaining materials, while severe refractive errors may call for rigid gas-permeable lenses, which can provide superior vision correction instead of “soft” lenses.
Lifestyle is another matter to be discussed with your ophthalmologist. If you don’t have time to bother with regular lens cleaning and maintenance and you can get good results from soft lenses, we may suggest single-use disposable contacts. If you hate constantly putting in or taking things out of your eye, extended-wear contacts can minimize this hassle for you.
How Should I Prepare for a Contact Lens Eye Exam?
- You may be dilated and may need someone to drive you home.
- Bring your glasses and contact lenses if you wear them.
- Bring any eye medications and a list of all other medications with you.
