The contact lens services available at B-Town Eyecare include the fitting and management of contact lenses for refractive conditions such as nearsightedness, farsightedness, astigmatism, and presbyopia. Each of these conditions can be treated with a variety of lens types and materials. Our office provides care for those individuals with medically necessary contact lens needs, such as Keratoconus, Post Corneal Transplant, or an irregular corneal surface.
Contact Lens Evaluations
The goal of contact lens evaluation is to find the most appropriate contact lens for your optimal comfort and vision. An enormous variety of types, styles, materials, sizes and colors are offered. We are committed to taking the time and making the effort to fit you properly. Although many patients need only one fitting session, some require additional visits. In our experience, the extra time, effort and patience are very worthwhile, both for your ultimate satisfaction and the health of your eyes.
Insertion and Removal Training Session
During the appointment, we will provide personalized instruction in the safe care and usage of your new lenses. Should further time be required, we will be happy to schedule an additional session without charge. Upon completion of a successful insertion and removal session, you may begin wearing your lenses and we will schedule your first follow-up appointment.
You will also understand the importance of adhering to the proper lens care procedures and instructions. Understanding the necessity for scheduling and keeping your appointments can prevent damage to your eyes or contacts.
One or more follow-up appointments will be necessary to assure that your contact lenses continue to fit well and your eyes remain healthy. Charges for follow-up visits during the first six weeks are included in the contact lens evaluation fee.
Contact Lens Evaluation Fee
The fitting of contact lenses requires additional professional decision-making than that of a regular eye examination. This additional fee is additional to the eye examination fee and is not typically covered by eyecare insurance. The contact lens evaluation fee includes up to six weeks of additional visits to optimize the contact lens prescription.
Many lens designs are available to correct various types of vision problems:
Spherical contact lenses are the typical, rounded design of contact lenses, which can correct myopia (nearsightedness) or hyperopia (farsightedness) and are available in virtually all materials and replacement schedules.
Bifocal or Multifocal contact lenses contain different zones for near and far vision to correct presbyopia (the need for a different distance and reading prescription). There are both soft contact lens bifocal designs and rigid gas permeable lens design. Some lenses contain a visible segment area for near viewing, while others incorporate the progressive
or no-line design. Selection is based upon the type of lens which will provide the most stable and comfortable vision specific to your needs. Some lenses contain a visible segment area for near viewing, while others incorporate the progressive or no-line design. Selection is based upon the type of lens which will provide you with stable and comfortable vision specific to your needs.
Monovision/Modified Monovision is a method where both eyes see but most of the work for reading is done by one eye and the other does most of the work for distance activities. is a good alternative at times to multifocal lenses and is also used in LASIK surgery for some individuals.
Orthokeratology lenses are specially designed to reshape the cornea during sleep, providing lens-free daytime wear. More coming soon!
Toric contact lenses correct for astigmatism, as well as for myopia and hyperopia . They are now available in all types of replacement schedules and materials. Numerous advances in product design have improved the fit, vision and comfort. All of these lenses can be custom made for hard-to-fit eyes. Many other additional lens designs are available. Typically these are less common and fabricated for use in special situations, such as correcting for keratoconus.
There are three types of materials that contact lenses are made from:
Soft Contact Lenses (SCL)
This type of contact lens is relatively soft and flexible, which allows it to drape over the entire surface of the cornea like a blanket. There have been many advances in technology and materials in the past few years, making contact lens wear healthier for the eye and more comfortable for the patient. Advantages of this type of lens include disposability, shorter adaptation time, and the ability to enhance or change eye color.
Here are some types of soft lenses:
Daily wear Contact Lenses
You wear these when you are awake and remove them when you go to sleep. Many are disposable, meaning that you wear a new pair of contacts each day. Or you might choose contacts that last longer and only need to be replaced once a week, every two weeks or every month.
Extended Wear Contact Lenses
You can wear these while you sleep, but they need to be removed for cleaning at least once a week. Fewer eye doctors recommend these contacts because they increase the chance of getting a serious eye infection.
Toric Contact Lenses
These can correct vision for people with astigmatism, though not as well as hard contact lenses. Toric lenses can be for daily or extended wear.
Tinted Contact Lenses
Many of the types of lenses described above also come in colors that can enhance the natural color of your eyes or totally change the eye’s appearance, as in from brown to blue. They are also available in 1-day disposable materials for that occasional special event or for a new look!
Cosmetic (Special Effect) Contact Lenses
These lenses change the look of your eye and many can also correct vision. They include colored contacts and lenses that can make your eyes look like vampires, animals or other characters.
Regardless of whether you are using cosmetic contact lenses for vision or not, you need a prescription for decorative contacts. To avoid getting dangerous eye infections, these lenses must be treated like prescription contacts. This means cleaning them regularly and thoroughly as directed.
Please be aware: Decorative contact lenses can lead to serious eye problems.
Rigid Gas Permeable Lenses (RGPs)
The most common type of hard contact lens is a rigid gas-permeable (RGP) lens. These lenses are usually made from plastic combined with other materials. They hold their shape firmly, yet they let oxygen flow through the lens to your eye. RGP lenses are especially helpful for people with astigmatism and a condition called keratoconus. This is because they provide sharper vision than soft lenses when the cornea is unevenly curved. People who have allergies or tend to get protein deposits on their contacts may also prefer RGP lenses. These lenses are usually about eight millimeters in diameter, which is smaller than the colored portion of the eye. They also help to slow down the progression of nearsightedness or myopia.
Hard lenses are made from a type of plastic called PMMA and are virtually obsolete and rarely used.
The amount of time a lens is worn each day and the frequency with which it is replaced is dependent upon many factors, such as doctor’s recommendations, ocular health of the eye, patient convenience and compliance with lens care regimen. Realistic patient expectations about lens performance and the maintenance of good ocular health are among the primary goals for successful contact lens management.
Daily Wear: With this schedule, the lenses are worn for an average of 12 hours per day and then removed at night. After removal, the lenses are cleaned, disinfected, and stored prior to re-insertion the following morning.
Extended Wear: These lenses may be worn overnight for 1-6 consecutive nights. Soft contact lenses in this category generally have a higher oxygen permeability than daily wear contact lenses and are made of silicone hydrogel material. This wearing schedule can create a greater risk (8 times greater compared to the daily wear schedule) of infections, including sight threatening corneal ulcers. Some RGP’s can also be used on an extended wear basis. An example of this is in orthokeratology.
Daily Disposable Lenses: Disposable lenses are designed to be discarded upon removal rather than cleaning, disinfecting and storing the lens. A fresh lens is used each morning. Some advantages of this modality are that a new lens is placed on the eye every day and there is no need for solutions.
Frequent or Planned Replacement Lenses: This category includes 2-week, 1-month, quarterly and 6-month replacement lenses. These lenses must be cleaned and disinfected each night prior to storing. Planned or frequent replacement schedules can be beneficial for patients who experience comfort and vision problems created by excessive lens deposits, typically protein build-up. The insertion of a fresh lens can relieve these symptoms as well as reduce the potential for inflammation or infection.
Treatment of certain patients with corneal dystrophies or degenerations such as Keratoconus may involve the use of specific RGP or specialty soft contact lens designs. Post-surgical and post-trauma patients can also benefit from contact lenses designed for their specific needs. Post-surgical or therapeutic contact lenses are an effective treatment for patients that have undergone corneal surgery and have experienced complications. Suboptimal visual acuity is the most common result of corneal surgery complications. Frequent causes of reduced visual acuity may be due to numerous reasons such as:
Some of the most common uses of post-surgical contact lenses are:
The services we offer in our clinic include contact lenses for a wide range of conditions that include:
Keratoconus and Pellucid Marginal Degeneration: This is a non-inflammatory, self-limiting corneal disease involving progressive thinning, steepening, and distortion of the cornea. The resulting loss of optical quality in the cornea is improved best with RGP lenses specially designed for the patient.
Post-Surgical: Patients who have had refractive surgery such as RK, PRK, and LASIK may need to improve their vision to a more desirable level with contact lenses in some cases. For patients who have had non-refractive surgery, such as a corneal transplant, a contact lens may be the best way to enhance vision.
Aphakia: Both pediatric and adult aphakia is the absence of a lens inside the eye.
Post-Trauma: Corneal defects (such as abrasions, recurrent erosions and lacerations) caused by the introduction of a foreign body or substance into the eye may be managed with the use of contact lenses.
Aniridia: Absence of an iris. Patients with iris abnormalities from trauma or congenital forms like anirida can benefit from prosthetic contact lenses which artificially simulate the pupil. Opaque contact lenses can also be used as an alternative for patching in Vision Therapy.
Scleral contact lenses can help people who don’t respond to other treatments for their cornea conditions. A scleral lens differs from a standard contact lens — it’s larger and rests atop a layer of tissue over the white part of the eye (sclera). A fluid barrier keeps the scleral lens from touching the cornea.
The lack of contact between the back of the scleral lens and the cornea reduces pain. And the spherical front surface of the lens improves vision.
Scleral lenses are sometimes the only solution for people with conditions that can’t be helped by regular contact lenses. Scleral lenses can be used to:
Lenses can be customized for each person.
There are many different options when it comes to using contact lenses to improve surgical outcomes. The approach taken depends on numerous factors and the lenses used may be soft lenses, gas permeable lenses, hybrid lenses, or scleral lenses.
At B-Town Eyecare improving the lives of patients with post-surgical and keratoconic lenses is a big part of what we do. Our doctors see patients with advanced corneal problems every day requiring the hi-tech instrumentation and skill available at our office.
We not only have the state of the art equipment to accurately fit your lenses but, unlike most eye doctor’s offices, we have diagnostic lens sets for a wide array of therapeutic applications allowing us to more quickly and accurately find a solution that works for you.
Having diagnostic lens sets onsite not only saves time but also lets you see what your new lens will feel like.
