Keratoconus Treatment In Mumbai

During the early stages of keratoconus, contact lenses and eyeglasses can provide good vision. Refractive surgical options are very rare and not usually recommended due to very important aspects related to keratoconus. Cornea mapping technology, for example – topography, is one of several diagnostic tests that is performed to gather important information about your cornea to help determine the best treatment option for your unique case.

Become well informed of all your options! Lack of knowledge often creates fear, so learn all that you can about this condition. Ask questions and discuss your concerns with your doctor and follow his/her instructions.

Contact Lens Designs For Keratoconus

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 situation to find the lens that offers the best combination of visual acuity, comfort and corneal health.

Aspheric lens designs gradually flatten from the center toward the periphery, approximating the steep cone vs. flat periphery curvature relationship seen in keratoconus. These designs are indicated for small to moderate nipple cones. The goal of this lens is to vault the apex of the cone, or lightly touch it, and align the more normal peripheral cornea. Because the nature of an aspheric lens allows for plus power in the periphery, presbyopic keratoconics may find this lens preferable if the fit is acceptable. The lens needs to center for the optics to work.

Specialty Contact Lens Designs For Keratoconus

  • Epicon lens is a large, semi-scleral lens made of a new material called carbosilfocon. It is a moldable, flexible material with the health benefits of an RGP lens and comfort approaching that of a soft lens. It is distributed by Specialty Ultravision.
  • Flexlens Tricurve Lens is a soft contact lens designed with a thick center that creates more rigidity to maintain visual acuity.
  •  Infinity Cone by Infinity Optical, Inc. is designed to fit the periphery of the lens on the outer edge of the cornea as far away from the cone protrusion as practical.
  • McGuire lens system, a modification of Soper’s design, was introduced in 1978. It is manufactured with a number of blended curves on the back surface of the lens.
  •  Menicon Decentered OZ design has four spherical curves on the back surface of the lens with the optical zone decentered approximately 1mm. This is a good design for a low, sagging cone.
  •  Piggyback lens system consists of two lenses – a soft lens that rests against the cornea and an RGP lens worn right over it.
  • Rose K is a lens design with a complex, computer generated peripheral curve system designed by Dr. Paul Rose of Hamilton, New Zealand. It is distributed by Lens Dynamics, Inc.
  •  SoftPerm lens (replaced the Saturn lens) has a rigid center made of RGP material and soft outer rim, or skirt, made of soft lens material. It is available now from CIBA.
  • Scleral (or Haptic) lenses have been around since the 1800’s. With the development of highly oxygen permeable polymers they are again becoming an option for KC. This is a large lens that rests on the sclera (the white part of the eye) and vaults over the cornea with little or no touch. This lens is more popular in Europe than in the US.
  • Computer assisted contact lens designs are available from some laboratories. Because they are designed from corneal topography, and the keratoconic cornea can have changes in curvature that are too detailed for the corneal map to reveal, this type of design may or may not work when the lens is placed on the eye and interacts with the ocular environment.

At Clear Vision we have a vast array of lens systems to help our keratoconus patients successfully find one that fits them well. We are one of the few centers in India that offer a full range from regular RGP lens fits to the scleral lenses.Visit for Keratoconus specialist in mumbai at Clear Vision.
