Contact lenses are a wonderful alternative to traditional eyewear. They’re comfortable and convenient, even if they do require a little extra maintenance. And if you have sensitive eyes, you can try specialty contacts like scleral lenses! But what should you expect when you’re thinking about trying scleral lenses?
First, your optometrist will work through a consultation. They’ll examine your vision and eye health to determine how to correct your vision. They’ll perform a series of tests and give you an updated prescription. At the end of the exam, they’ll likely provide a trial pair of scleral lenses to take home for a week or so. This makes sure your future contacts truly meet your unique needs.
What Are Scleral Lenses?
Scleral lenses are a type of specialty contact lenses. Unlike traditional contacts—which rest on the eye—scleral lenses are a large, arching option.
These lenses don’t make any contact with the cornea. Instead, they rest on the sclera (the whites of your eyes) and arch over the cornea. This leaves a small gap underneath for saline and your natural tears.
Due to their unique shape, scleral lenses are a great treatment option for corneal conditions or sensitivity. They’re ideal for:
- Dry eyes
- Astigmatism
- Keratoconus
- Overall sensitivity
If other contacts cause irritation or discomfort, scleral lenses may offer the relief and clarity you deserve. So how do you get them? It all starts with a contact lens fitting and exam.
What Is a Contact Lens Exam?
A contact lens exam is similar to a regular comprehensive eye exam. However, the goal is different—instead of glasses lenses, these exams focus on finding the specific prescription for contact lenses. You should book a contact lens at least once per year to stay on top of your eye health.
During your exam, your optometrist evaluates the health of your eyes, your prescription, and any factors that could affect the process. Typically, your optometrist will:
- Measure the curvature of your cornea to determine the lens shape.
- Assess the tear film of your eyes to evaluate dryness.
- Use corneal topography to map the surface of your eye.
- Check your prescription for accuracy with retinoscopy or similar tests.
- Test how lenses settle on your eye to ensure a proper fit.
These are all essential. They identify problems that otherwise could go unnoticed. Then, your optometrist can create your specific prescription for your future scleral lenses.
What Can Be Detected During a Contact Lens Exam?
During a contact lens exam, your optometrist will be looking for more than just a prescription. They’ll determine any potential conditions that affect the effectiveness of a contact lens. Your optometrist can look for:
- Dry eye and tear film imbalance
- Corneal irregularities
- Signs of eye infections
- Allergies impacting the eyes
- Changes in vision prescription
This testing is designed to be non-invasive, safe, and thorough. With this information, your optometrist can give you a prescription that truly meets your needs.
What to Expect from a Contact Lens Exam
Your exam starts the moment you walk through the door. Your optometrist will tailor the contact lens exam to meet your unique needs. Then, they’ll use this information to give you an updated prescription for your scleral lenses.
Before the Exam
First, you’ll need to prepare for the exam itself. It helps to:
- Write down any unusual symptoms you’ve recently experienced
- Bring a list of any medications or supplements you’re currently taking
- Make note of any changes in your vision or comfort with your current lenses
- Know your family’s eye health history—it may be relevant to your exam
- Remove your contact lenses a few hours before the appointment, if instructed
- Bring your current glasses or contact lenses to the appointment
These steps beforehand are key to a smooth and effective contact lens exam.
During the Exam
The exam process itself is thorough but straightforward. Your optometrist performs a series of tests that measure your cornea, your visual clarity, and your overall eye health.
To do this, your optometrist will work through non-invasive testing like:
- Corneal topography to map the curvature of your cornea
- Refraction assessment to determine your precise prescription
- Slit-lamp examination to evaluate the health of your eyes
- Tear film evaluation to check for dry eye conditions
Once done, your optometrist will give you a trial lens. This is to test the overall fit and comfort of your new lenses. They’ll examine how it interacts with your eye to make sure it stays stable—and properly corrects your vision.
After the Exam
Once testing is complete, your optometrist will discuss your results. If either of you have any concerns, this is the time to mention it. Then, they’ll go over how to care for your scleral lenses.
Typically, this includes:
- Proper cleaning and storage techniques
- Instructions on how to insert and remove the lenses safely
- Tips for maintaining good hygiene to prevent infections
You’ll likely receive a pair of lenses to take home for a week or so. These are another set of trial lenses to make sure your lenses suit your day-to-day needs. You’ll return a week or two later to discuss the results and make any adjustments if needed.
