Scleral Contact Lenses

What are scleral lenses?

Scleral lenses are custom, large diameter gas permeable (GP) contact lenses. They are much bigger than most GP lenses, so they completely “vault” over the cornea and rest on the white part of the eye called the sclera. Unlike soft contact lenses and conventional gas permeable lenses, sclerals do not touch the cornea. They tuck underneath both eyelids making them more comfortable to wear.

Why wear scleral lenses?

  • Scleral lenses are made out of highly oxygen permeable GP materials.
  • They are made exactly for your visual needs to give you customized vision correction.
  • They are durable and may last for one to two years.
  • They provide extra moisture for healthy eyes and for people who have severe dry eyes.

Since scleral lenses are designed to vault over the cornea entirely, they create a fluid filled space between the back surface of the lens and the cornea. The cornea stays moist enhancing ocular comfort.

Irregularly shaped corneas, such as in keratoconus, past corneal surgery, or previous corneal injury, may prohibit good vision with glasses or disposable soft contact lenses. Scleral lenses counteract the shape of the cornea by creating a fluid filled chamber or “tear lens” between the irregular corneal surface and the back surface of the contact lens.

Additionally, scleral lenses provide comfort comparable to, and in some cases, superior to soft contact lenses. Unlike standard small gas permeable contact lenses, scleral lenses are not prone to shifting or “popping” out of place.

Who can benefit from scleral lenses?

Patients that have irregular corneas, severe dry eye/ocular surface disease, and patients with a refractive error not sufficiently managed with other forms of correction can benefit from improved vision with scleral lenses. Some conditions in which patients benefit from scleral lenses include but isn’t limited to:

  • Keratoconus
  • Pellucid Marginal Degeneration
  • Severe Dry Eye/Sjogren’s Syndrome
  • Neurotrophic Keratopathy
  • Ocular Cicatricial Pemphigoid
  • Post-Radial Keratometry
  • Post Corneal Transplant
  • Salzmann Nodular Degeneration
  • Post-LASIK ectasia
  • Terrien’s Marginal Degeneration
  • Scarred Corneas
  • Exposure Keratitis (such as Bell’s Palsy)
  • Limbal Stem Cell Deficiency
  • Corneal Dystrophies
  • Myopia/Hyperopia/Astigmatism

Lens in the eye

Scleral lenses vault the cornea and land on the sclera, or the white of the eye, being similar in diameter to a soft contact lens.

Dr. Andrzejewski and Dr. Malooley have fit many patients in scleral lenses with great success and want to help you see your absolute best. If you have been told you need a gas permeable or “hard” contact lens to improve your vision or are interested in an evaluation to see if you can benefit from scleral lenses, call our office to schedule an assessment.

How do insert and remove my scleral lenses?

Always follow the care instructions your eye care provider gives you. If you are struggling with insertion and removal of your scleral lenses you can watch videos at:


LASIK , or Laser-Assisted In Situ Keratomileusis, is a surgical procedure that is designed to reduce your dependency on glasses and contact lenses. Here at Chicago Cornea Consultants, Ltd., our LASIK surgeons use the latest in laser vision correction technology to ensure each patient receives optimal results.

Traditionally, presbyopia, which happens to all of us as we age, has always meant glasses for clear reading vision. It's a condition not even correctable by laser vision correction. Luckily, there is an option. Refractive lens exchange allows patients a clear alternative to reading glasses and is capable of reducing or eliminating presbyopia by using an advanced multifocal intraocular lens.

Keratoconus describes a cornea that weakens as collagen fibers deteriorate, causing the cornea to adapt a cone-like shape. Keratoconus can cause blurred vision, light sensitivity, glares, and decreased night vision. In its early stages, keratoconus may be treated with the use of prescription glasses or contact lenses.  Keratoconus is also one of the most common reasons for corneal transplant, and one of the most successful. call any of our offices and ask to speak to the Vision Correction Surgical Coordinator, or use the contact form below.

It's estimated that a million or more Americans have glaucoma and don't even know it.  People with glaucoma often do not experience any symptoms until they begin losing their peripheral vision. One of the scariest things about glaucoma is that it usually has no symptoms in the early stages, earning glaucoma the name "silent thief of sight." Anyone can be at risk, so it's important to have your vision regularly examined.

At Chicago Cornea Consultants, our doctors take great care in maintaining ocular health for our patients. However, a number of our patients voice concerns regarding soft lines and wrinkles around the eyes and other regions of the face. We have responded by introducing cosmetic procedures like BOTOX® Cosmetic through our Chicago practice.

Loss of near vision, or presbyopia, happens when your natural lens loses elasticity, making it difficult to change your focus to see objects up close.  It affects most people in their 40s and early 50s. The hassle and inconvenience of readers is driving many patients to look for a better way to improve their near vision without glasses. The Raindrop Near Vision Inlay is a simple solution to presbyopia. This innovative and unique procedure is an effective alternative to the hassle of readers. Raindrop Near Vision Inlay is a minimally invasive and long term solution to improve near vision without glasses.
