Just about anybody with a refractive error is a candidate. Dr. Gemoules has successfully treated patients seeking relief from:
- Halos, glare, starbursts and other higher order aberrations following unsuccessful corneal refractive surgery such as LASIK, PRK, RK and other.
- Penetrating keratoplasty
- Keratoconus
- Dry eye disorders
- Corneal scars and other diseases
Although many of our patients have come to us post-operatively following LASIK, PRK, and RK procedures, we have also brought relief and improved vision for inhcreasing numbers of patients who have corneal transplants, high astigmatism, irregular astigmatism, dry eye disorders and corneal scars.
Patients with keratoconus, pellucid marginal degeneration, and other ectasias are also prime candidates for our lenses. These patients are frequently unable to achieve good vision with eyeglasses or soft lenses, and often struggle with discomfort and fluctuating vision of traditional hard or GP lenses.
Athletes find scleral lenses provide improved vision while reducing dryness and offering increased protection for the cornea from dust and debris.
“I just came back from Dallas, where I met Dr. Gemoules for a fitting in order to solve my Higher Order Aberration issues and also recover a good visual acuity. In only two days, Dr. Gemoules has succeeded in providing me an excellent vision, night and day, with very good contrast. I'm very happy. Moreover, the comfort of these lenses is unbelievable; I can barely feel them on my eyes, so I can wear them about 14 hours a day!”
How do our lenses work?
We specialize in prescribing, designing and fitting several types of custom-made
gas-permeable contact lenses for our patients – Intra-limbal and
Scleral lenses.
The
Gas Permeable (GP) contact lens with its smooth, rigid optics creates a new refracting surface
atop of the patient’s irregular and asymmetrical cornea thereby
reducing corneal aberrations and improving vision. Our lenses embody the unparalleled optics of the
GP lens with the comfort of a soft lens, making them ideal for therapeutic use. While the lens itself is a superior product, it is the meticulous measurement of corneal irregularities and the accuracy of the design and fit of the lens which is responsible for enhanced comfort and visual correction.
Scleral lenses are helpful to patients who suffer from the irregular astigmatism that often goes along with corneal transplantation. Those who do not enjoy clear vision with soft lenses due to astigmatism or an irregular cornea, and who cannot tolerate traditional
corneal GP lenses would be considered ideal candidates for our mini-scleral
or scleral designs. The lens is also available in a non-translating multi-focal for presbyopes.
Millions of people worldwide suffer from dry eye conditions, often accompanied by severe pain. When all other options have been exhausted, many of them can benefit from the corneal protective effects of a scleral lens. GVH, or graft vs. host disease is one example. Sjögren's syndrome is another. Patients who experience reduced wearing time and discomfort from their
ordinary contact lenses may also benefit from the mini-scleral design.
Patients should plan on one full week to complete the assessment and contact lens fitting. Our lenses are manufactured according to each individual’s specific and unique needs. This process often requires several trials before a fit is finalized. Our most recent advances in equipment and design procedures are bringing us much closer to a perfect first fit.
The initial assessment takes about two hours and includes a detailed history as well as wavefront analysis of the eyes using the latest technology in ray-tracing aberrometry, topographical analysis comparison of corneal versus internal aberrations in the visual system, visual acuity assessment, careful refraction and initial trials with contact lenses to determine the best fit and power. At the end of the assessment, lenses are ordered for receipt the following day.
The fit and power of the initial set of custom-made lenses are carefully analyzed. With the lenses in place, wavefront aberrometry is again performed and typically reveals a 65 - 80% reduction of the total higher order aberrations. Often adjustments can be made in the office and the patient leaves wearing the lenses that very day to try in the “real world.” Patient feedback as well as physical examination of the lenses on the eyes will reveal any need for adjustment and redesign of the lenses, which again will usually take one day.
Dry eye diagnosis and treatment, including punctal occlusion, can be initiated during the visit.
When more surgery
is not an option, either because of anatomical constraints, technological
limitations, or patient fears, it is comforting to know that a viable
non-surgical solution is available.
NOTE: Prior to the assessment, patients should forward records such as preoperative topographies, wavefronts, operatives notes, etc. from their previous treatments. We also request that patients review and sign the Informed Consent Form.
As our name implies, many Global Refractive Solutions patients come from across the United States and around the world. Working with a major contact lens manufacturer who is physically located in the Dallas area permits a quick turnaround of prescription changes and enables most patients to complete the fitting process within five business days. On very rare occasions, a second week is required. If the patient is from outside the area, he or she must arrange continuing care upon returning home.
