Contact Lenses

 

 

Soft Lenses

 

Contact Lens InsertionDaily Wear Lenses

These are standard soft contact lenses that are worn up to 16 hours per day, but never overnight while sleeping. Nowdays, virtually all soft contact lenses are disposable. Most commonly, the patient disposes of the lenses either every 2 weeks, or on a monthly basis, depending on the lens our doctor fits.

Daily wear soft contact lenses are for patients who either have very little, or no astigmatism in their prescription. Dr. De Rubeis uses a multitude of different types and brands of lenses depending on your prescription, the curvature of your eye, the size of your cornea, and other factors such as tear production and quality. This allows him to get the "perfect fit" on every patient.

Biofinity Contact LensesNight and Day ContactsExtended Wear Lenses

These are disposable soft contact lenses that allow up to 6 times as much oxygen transport as standard lenses through to your eye. Your eye needs to breathe. If your eye does not get enough oxygen, the cornea will swell. This increases the chance of getting an infection because the cells of the cornea, which acts as a barrier against bacteria and viruses, becomes broken down. Serious infections, such as corneal ulcers, can result which can be very painful and can even lead to scarring, loss of vision, and blindness. Therefore, we need lenses that allow enough oxygen to eliminate corneal swelling (or edema).

Today, we have lenses which allow enough oxygen for overnight wear. These lenses can be worn only during the day (for patients who are awake long hours), occasionally overnight, or on an extended wear basis up to one month at a time.

Toric Soft LensesToric Soft Lenses

For patients who have astigmatism, we use "toric" lenses. Toric Soft Contact Lenses have come a long way since their inception in 1977. Today, soft torics are available in disposable lens materials and are much more stable on the eye and more reproducable to ensure that every lens fits the same way.

Toric lenses are "weighted" at the bottom with a thicker, prism ballast which allows gravity to keep the lens from rotating on your eye. In this way, we can correct even larger amounts of astigmatism and ensure that you see to your greatest potential. For patients with very large amounts of astigmatism, custom made soft toric lenses can be fit allowing even more control of the patient's axis and power of astigmatism.

Wild Eyes Tinted Contact LensesTinted Soft Lenses

Tinted soft contact lenses are available in "enhancer" tints to accentuate you own eye color. They are also available to drastically change your eye color from brown to blue, green, or even custom "halloween" or "hollywood" type tints. These lenses can be fit just for fun and allows you to match you mood for the day or even your wardrobe. Today, you eyes can be virtually any color you want.

Tinted ContactsTinted lenses can be also used to mask eye abnormalities or injuries making a scarred or deformed eye look cosmetically appealing again. These lenses are generally fitted to the patients eye first using clear lenses. Then, once the doctor is satisfied that he has a well fit contact lens, the lens is tinted cosmetically. Often, these lenses are hand painted to match photographs of the opposite eye. We also use tinted lenses of this type in one eye only for patients who have color deficiencies. This allows the color deficient patient to recognize subtle differences in brightness to distinguish colors of objects or lights that they would ordinarily not be able to see.

Bifocal Soft Contact LensBifocal Soft Lenses

Bifocal soft contact lenses were first introduced in 1982. The designs have been improved over the years making them a viable alternative to wearing reading glasses over your contact lenses or wearing "mono-vision" contact lenses.

Dr. De Rubeis often fits patients for mono-vision which , traditionally, has a very good success rate. This allows the patient who is over 40 years of age and needs bifocals to read or use a computer to see distance and near objects using only their contact lenses. This frees them from depending upon reading glasses. Bifocal soft lenses can often work well for these patients and has the additional advantage of being able to use both eyes together as a "team". In other cases, our doctor will choose to fit "modified mono-vision" which is a combination of bifocal soft lenses and mono-vision.

 

 

 

Rigid (Gas Permeable) Lenses

 

RGP contact lens insertionSpherical Gas Permeable Lenses

Rigid Gas Permeable (RGP) contact lenses are today's version of "hard" contact lenses, but that is where the comparison stops. Today, they are made of a type of plastic material using silicone polymers which make them the most oxygen permeable lenses in the world. They often provide the patient with sharper vision, are more durable, easier to care for, and less likely to cause infections than soft contact lenses. Because they last longer, they can also be less expensive than soft lenses in the long run. The only drawback is the initial comfort of the lens.

RGP lens on fingerA patient needs to adapt to wearing an RGP lens. Your eye itself does not feel the contact lens, but your eyelid must adapt to gliding over the RGP lens with time. This is similar to feeling a watch or a bracelet on your wrist when you first start wearing one. After a short period of time, you no longer feel it. This period of adaptation generally takes about 3 weeks.

RGP lenses also wet better than soft contact lenses which makes them the best lenses for patients with dry eyes. Because they are always custom made specifically for your eyes, they can be used to fit a larger range of patients and prescriptions including patients with medical conditions such as keratoconus and post-op corneal transplants.

RGP Fluorescein PatternToric Gas Permeable Lenses

For patients with large amounts of astigmatism, their corneas (the front surface of the eye) are shaped very much like a football. In order to allow a contact lens to fit properly to the contour of these oval shaped eyes, our doctor will design a "back toric RGP" contact lens. Toric RGP lenses allow the lens to fit both meridians of your cornea exactly. In other words, the lenses end up fitting "like a glove". The end result is a very comfortable contact lens that completely corrects even extremely large amounts of astigmatism and usually allows the patient to see sharper vision than possible even using eyeglasses.

Even if you have been told you cannot wear contacts because you have too much astigmatism—most likely our doctor can fit you with a Toric RGP successfully. Other doctors typically do not fit these types of lenses because they are complex and tricky to fit, but Dr. DeRubeis has been fitting them with great success for over 25 years.

Bifocal RGP lensBifocal Gas Permeable Lenses

Unlike soft bifocal contact lenses, Bifocal RGP's have a high success rate when fit by an experienced doctor. The lenses are available in many different designs. Today, Dr. De Rubeis typically uses a concentric progressive design where the reading portion of the lens completely surrounds the distance portion. This peripheral "reading area" contains a progressive type bifocal add power which gradually gets stronger just like custom progressive spectacle lenses.

Bifocal RGP's allow us to fully correct your distance vision even if you have larger amounts of astigmatism while eliminating the need for wearing reading glasses in most cases. The result is a freedom from constantly wearing eyeglasses combined with one of the safest methods of contact lens wear available today.

Keratoconus eyeSpecialty Gas Perm Lenses

In some cases, patients have unusually shaped corneas due to medical conditions such as Keratoconus, injuries, birth defects, dystrophies, and even surgical procedures like corneal transplants.

Keratoconus is a degenerative disorder of the cornea. The patient's cornea over time becomes "cone" shaped or bulges forward near the center. This results in distorted and reduced vision. In many cases, spectacle eyeglass lenses cannot correct the vision of these patients. Using special custom designed Keratoconic RGP contact lenses, Dr. De Rubeis can succesfully fit even these types of unusually shaped eyes. The result is far better vision than possible with glasses and allows these patients to continue to work and live normal lives.

Corneal transplant patients often require a contact lens to be fit on their eye to regain usable vision after their surgery. Many times, in order to allow a contact lens to fit over the grafted cornea, Dr. De Rubeis will design a "scleral" RGP lens. These lenses are much larger and fit like a dome over the top of the entire cornea from limbus (the edge of the cornea) to limbus.

 

 

 

CRT (Corneal Refractive Therapy)

CRT Lenses While You SleepCorneal Refractive Therapy

CRT is one of the newest forms of Orthokeratology which is a procedure to reshape your cornea and correct your vision so you can see clearly all day without your eyeglasses or contact lenses. In June 2002, the FDA granted approval of Paragon's CRT lenses to be worn overnight for vision correction while the patient sleeps.

Now you can be free of both glasses and contact lenses during the day without surgery! CRT is a non-surgical therapy which reduces your myopia and moderate amounts of astigmatism to temporarily correct your vision during the day. The treatment is not permanent so, unlike with refractive surgery or LASIK, if you are unhappy with your results the treatment can be discontinued and your vision will return to its original state. You simply wear your lenses while you sleep, remove them in the morning and enjoy great vision throughout the day.
