The contact lens department at De Cure Center is well equipped to cater the requirements of all eye conditions.We provide basic and various speciality contact lenses. The basic contact lenses like Spherical soft lenses, Rigid Gas Permeable lenses and Toric lenses are available which can be given in patients who wish to avoid glasses due to cosmetic purpose or due to the profession itself. Also, the Cosmetic contact lenses, which enables one to enhance or change the eye colour are available with us.
The prosthetic Contact lenses, which can be used in patient’s who have corneal scarring(white spot) or abnormalities like loss of iris, large/ irregular pupil can be given these lenses which will mask the scars/other deformities at the same time will reduce glare and photophobia. The patient’s who require glasses for near and distance can be prescribed with Multi focal contact lenses, which will keep them free from glasses.
The patients who cannot tolerate RGP contact lenses, have an option of Hybrid lenses which provide comfort of Soft lens and vision clarity of RGP lens. We also have Refractive Surgery Specific(RSS) Contact lenses for patient’s who complaints of glare, distortions and ghosting of images/shadows after the refractive surgery. . Orthokeratology that uses contact lenses at night to provide a spectacle free day is also available with us.
The special focus of this department is on Keratoconus and all the currently available contact lenses for the management of this progressive condition such as Rose K lenses, Kerasoft contact lenses, Scleral and miniscleral lenses are provided here. Keratoconus is managed by many different contact lens designs. No one design is best for every type of keratoconus. Since each lens design has its own unique characteristics, the practitioner carefully evaluates the needs of the individual to find the lens that offers the best combination of visual acuity, comfort and corneal health.
Compliance is the key to long-term success for all contact lens wearers. It is even more important for keratoconus patients, since they are almost totally dependent upon contact lenses for all their visual tasks. After patients have been successfully fit with contact lenses, a high percentage of complications and adverse reactions are related to skipping or shortcutting the recommended procedure for cleaning, disinfecting, and storing their lenses. A study revealed that 27% of patients admitted that they don’t clean their lenses daily, and it is likely that an even higher percentage of lens wearers are non-compliant in some way. Some patients have used dishwashing liquid, baby shampoo, or even toothpaste instead of the recommended cleaners; stored their lenses dry, rather than in an FDA-approved disinfecting solution; and used saliva (which contains a host of sight-threatening microorganisms) instead of the sterile solutions that are readily available, to wet their lenses before inserting them in their eyes.
GLASSES
In the early stages, vision can be corrected with glasses or regular soft contact but as KC progresses they are not able to correct the distortion caused by the irregular corneal surface and more complex contact lens designs are required.
SOFT LENSES
The role of soft lenses in keratoconus is limited because the soft lens drapes over the irregular corneal surface and the front surface of the lens assumes the same irregular surface as the cornea without trapping a fluid reservoir so the effective refracting surface is no improvement over the original corneal surface. There are some specially designed thicker soft lenses retain more of a rigid shape and may contribute to the liquid lens effect to some extent. There are designs being used for keratoconus, and they are helpful in mild to moderate cases.
RGP CONTACT LENSES
Rigid Gas Permeable (RGP or GP) contact lenses are primary option for correcting KC vision. The rigid lens masks the underlying irregular cornea and functions as the new refractive surface of the eye, with the tear film filling in the space between the back of the contact lens and the front of the eye. “Rigid” defines the type of lens. “Gas Permeable” describes the lens material. There are many different RGP lens designs.
