Contact lenses can be a great alternative to glasses for full time wear or occasional use for sports or social events. The availability has grown to be able to fit people with astigmatism, people who need bifocals, dry eye patients and people with corneal problems. At our office we have the latest lens technology for astigmatism, high oxygen gas permeable lenses, and bifocal contact lenses.
Most soft contact lenses worn today are disposable. These lenses are replaced on a regular basis; every day, 2 weeks or 1 month depending on the brand and on your needs. Generally a supply of disposable lenses is purchased at one time. The trends in the contact lens industry are moving toward a more disposable market due to ocular health advantages and ease of care. Daily disposable lenses are one of the healthiest ways to wear soft contact lenses.
Almost all types of soft lenses have the capability of correcting astigmatism with what is called a toric lens. These are available in most powers. Many people are told they cannot wear soft lenses due to astigmatism. This is not the case; however, some people are better candidates than others.
Gas Permeable Lenses (GP)
Oxygen permeable lenses or GP’s are made from different plastics than soft lenses. They are smaller and fit the cornea differently. GP’s generally provide sharper vision than soft lenses. These lenses are very healthy for the eye and are the best way in most cases to correct astigmatism. They are best worn on a regular basis and one pair of lenses may last one to three years making them very economical. They are not disposable but can be polished in our office regularly if build up or scratches occur. These lenses are used to fit irregular corneas and patents with keratoconus. They can also be used on patients who have had corneal surgery.
Bifocal Contact Lenses
If you have over 40 eyes and are tired of wearing reading glasses, bifocal contact lenses may help you reduce your need for readers. Bifocal lenses are available in both soft and GP materials. These are a great alternative to wearing glasses. If you are a current Gas Permeable wearer, a bifocal can be designed for you in this type of lens. The vision is very natural and it is very easy to adapt to these lenses.
If you wear soft lenses or have never worn contacts then a soft lens bifocal may be a good option for you. These are available in many different brands and disposable modalities.
What Is Paragon CRT?
Corneal Refractive Therapy or CRT is nighttime vision correction that gives you freedom from glasses and contact lenses all day without refractive surgery.
CRT utilizes a specially designed therapeutic contact lens to gently reshape the cornea while you sleep. The lenses are removed when you awake and you are able to go throughout the day without correction. This is a temporary process. If you stop wearing the lenses, your vision will return to its original state within 72 hours.
How Long Will The Process Take?
Most patients will notice great changes in their vision within just 1-2 days but it may take 7-14 days to achieve optimum visual results. During this transitional period we will provide temporary soft lenses for daytime use if needed. Because you are able to see with your Paragon CRT lenses on, you may decide to put on the lenses during the day for a short time during this transitional period.
Who Can Wear CRT?
Paragon CRT is currently designed for individuals with low to moderate nearsightedness (up to -6.00 diopters) with or without astigmatism (up to -1.75 diopters). The great thing about CRT is that there are no age restrictions. Even children can benefit from this treatment and not have to deal with lenses during the day. We usually will start fitting children into regular contact lenses around age 10 at the earliest and the same would be true for CRT. Children or teens who are active in sports, tend to forget or lose glasses, or just won’t wear glasses are great candidates for CRT.
There are many people who have trouble with discomfort or dryness from wearing contact lenses during the day. Some people may not be ready for LASIK surgery or are not candidates for LASIK. CRT is a great option for these patients.
Is CRT Safe?
There is a small risk involved in wearing any contact lens. These may include increased risk of infection if not taken care of properly, corneal irritation and corneal swelling. In the FDA clinical study of CRT there were no serious adverse reactions.
How Long Do The Lenses Last?
It is recommended that the lenses be replaced about once a year. The lenses are a very high oxygen permeable lens and have a very precise design. Replacing the lenses regularly will ensure the best vision possible.
