Prosthetic Contact Lenses

Prosthetic contact lenses can greatly enhance the visual appearance of a damaged or disfigured eye, whether as a result of past trauma or a serious eye infection. By reducing glare and recreating a round pupil, the lenses can also help improve vision in circumstances where the pupil is irregularly shaped, whether owing to trauma, disease, or surgical error.

In certain circumstances, disposable cosmetic contact lenses provide the desired results.

However, if the eye shape prevents the prosthetic contact lens from maintaining on-eye stability, you will be referred for a prosthetic scleral shell. You may also need a personalized ocular prosthesis if your eye has been removed (enucleated).

Many individuals with deformed or scarred eyes can benefit from custom-made prosthetic contact lenses.

What are Prosthetic Contact Lenses?

Prosthetic contact lenses are special lenses that cover the cornea if the cornea has become opaque or cloudy. The unique lens is designed to blend in with the other eye. A customized and detailed paint-job is required to match the other eye and make the prosthetic eye look as real as possible. A birth defect, a disease process or eye trauma are some of the reasons one eye may not appear the same as the other.

Benefits of Prosthetic Contact Lenses

There are many benefits to wearing prosthetic contact lenses.

Provides cosmetic enhancement

Patients seeking soft prosthetic contact lenses are frequently interested in their cosmetic advantages. When they are fitted with the correct prosthetic lenses, their scars, disfigurements or congenital deformities can appear considerably less obvious.

Natural-looking

Prosthetic and aesthetic soft lenses are designed to look as natural as possible. At The Scleral Lens Center at Drs. Farkas, Kassalow, Resnick & Associates, we use a variety of techniques, ranging from translucent tinting to unique hand-painting, to make lenses that closely resemble the appearance, shape, size, color, and patterning of your natural eyes.

Boosts confidence

These lenses can boost a patient’s confidence and self-esteem. Eye injuries or deformities can have an impact on how patients feel, especially when interacting with others. Patients who wear cosmetic lenses that resemble the appearance of a natural eye tend to feel more at ease.

Helps with excessive light sensitivity

Photophobia, or light sensitivity, is a common side effect of many eye injuries. An eye injury can limit the eye’s capacity to filter light correctly. When the pupil is injured or altered, it can cause excessive pupil dilation or irregular pupil opening. Soft prosthetic lenses can help with light sensitivity by simulating a more natural pupil size and dilation.

Address problems with double vision

Double vision can also occur as a result of ocular trauma, either permanently or temporarily during recovery. Wearing an eye patch is one solution, but it has long-term implications for vision development and recovery, and it is neither the most pleasant nor the most unobtrusive option. Occluder prosthetic lenses can be created to have a black pupil that blocks light from one eye, preventing double vision.

Scleral Lenses For Visual Rehabilitation Following a Corneal Transplant

Tens of thousands of corneal transplants, or keratoplasty procedures, are performed every year. Several reasons explain why one would undergo keratoplasty.

  • Eye diseases or eye injuries that are left unmanaged or uncorrected
  • Severe cases of glaucoma, age-related macular degeneration or cataracts
  • Advanced stages of corneal degeneration or dystrophy

Essentially, a diseased cornea can lead to blindness without proper care from an eye doctor, and keratoplasty is meant to restore as much vision as possible. However, following the surgery, patients may experience vision problems and may require specialty contact lenses to see clearly and comfortably.

Post-Keratoplasty: Treatment & Recovery

Recovery from a corneal transplant might take up to a year, as the eye needs time to adjust to the new cornea. Many patients emerge from the surgery nearsighted or with astigmatism. Often, eye doctors will prescribe eyeglasses or specialty lenses to help with vision during this interim period that may at times have to carry on being worn after the eye has fully healed.

Visual Rehabilitation With Scleral Lenses

Keratoplasty frequently results in irregular corneal surfaces due to the transplant’s inability to fully adapt to the eye. Rigid gas permeable lenses (RGPs), hybrid contact lenses, or scleral lenses may be recommended to give a patient clear and comfortable vision without the need for additional surgery.

Scleral lenses are often the optimal choice, as the lens is designed to vault entirely over the cornea rather than rest on it. Scleral lenses allow a patient’s cornea to remain hydrated, provide clear vision, and avoid any risk of corneal scarring.

Contact The Scleral Lens Center at Drs. Farkas, Kassalow, Resnick & Associates to learn how scleral lenses can provide you with clear and comfortable vision following a corneal transplant.

What is Corneal Dystrophy and How Can Scleral Contact Lenses Help?

There are many different corneal dystrophies with overlapping symptoms. Among these symptoms is distorted vision due a misshapen corneal surface, more commonly referred to as corneal irregularity. Scleral lenses offer the perfect solution, as they even out the corneal irregularity, thus providing clear and sharp vision.

An eye exam at The Scleral Lens Center at Drs. Farkas, Kassalow, Resnick & Associates can examine your eyes and determine whether scleral lenses are appropriate for you.

What is Corneal Dystrophy?

Corneal dystrophy refers to a group of genetic and often progressive eye diseases characterized by the accumulation of abnormal material in at least one of the five layers of the cornea.

Most corneal dystrophies progress slowly and in both eyes. The age at which one can expect symptoms varies on a case-by-case basis.

Diagnosis of Corneal Dystrophy

An optometrist can usually detect the presence of corneal dystrophy with a slit lamp microscope during a regular eye exam. During this simple test the doctor shines a bright, thin beam of light into your eye. With the help of a slit lamp, discoloration or deformation of the cornea become visible. The exam can also show the build-up of abnormal material in the cornea.

The eye care professional will look into your family history of eye diseases, as corneal dystrophies are generally inherited. In some cases, genetic testing can reveal whether you are affected.

eye layersSymptoms of Corneal Dystrophy

People with corneal dystrophy may not experience any symptoms, while in others, the disorder may lead to significant vision impairment. Vision can be affected by the irregular shape of the cornea, as light is not bent correctly onto the retina. In addition, the accumulation of foreign material within the cornea can cause it to become foggy. In many cases, patients experience recurrent corneal erosion. This occurs when the top cell layer (the epithelium) detaches from the layer beneath.

Common symptoms for most corneal dystrophies include:

  • blurred vision
  • increased sensitivity to light (photophobia)
  • the feeling of having a foreign object in the eye
  • itching, pain, or severe discomfort
  • vision loss

How Can Corneal Irregularities Be Treated?

Traditional soft contact lenses cannot correct vision, as the lens merely takes on the irregular shape of the eye surface. Similarly, regular eyeglasses provide improvement only for moderate astigmatism; however, in high irregular astigmatism, eyeglasses are not able to correct the condition.

Corneal erosion may be treated with medication, such as antibiotics, lubricating eye drops, or ointments, to repair damage to corneal tissue. Laser treatment may be applied, or, in severe cases, a corneal transplant may be required.

Rigid Gas Permeable (RGP) lenses for Corneal Dystrophies

RGPs can correct a patient’s vision since the inner surface of these lenses can be adapted to the irregular cornea, while the outer surface maintains a smooth round shape, thus correcting refraction at each point of the cornea.

Scleral Lenses for Corneal Dystrophies

Scleral lenses offer clearer vision than RGP lenses as they vault over the corneal irregularity, forming a smooth dome-shaped surface. They are larger in diameter and rest on the sclera, the white part of the eye surrounding the cornea. The dome-shaped scleral lens spans over the cornea, creating an optically perfect surface with a liquid-filled vault underneath.

In addition, the lens is more comfortable to wear than most other lenses. The larger diameter prevents it from moving around on the eye, and the extra liquid between lens and cornea ensures that the eye remains well lubricated.

Types of Corneal Dystrophies

There are around 20 different types of corneal dystrophies, which can be divided into three distinct categories:

Anterior Corneal Dystrophies, which affect the outer layers of the cornea. These include Map-dot-fingerprint dystrophy, Lisch dystrophy, Meersman corneal dystrophy, Reis-Buckler corneal dystrophy and Thiel-Behnke corneal dystrophy.

Stromal Corneal Dystrophies, which affect the central or stromal layer of the cornea. These include granular corneal dystrophy, Lattice corneal dystrophy and macular corneal dystrophy.

Posterior Corneal Dystrophies, which affect the innermost layers of the cornea. These include congenital hereditary endothelial corneal dystrophy, Fuchs’ corneal dystrophy, posterior polymorphous corneal dystrophy and Schnyder crystalline corneal dystrophy.
