Dot matrix stabilization with the piggyback lens system.

BACKGROUND: The piggyback system of contact lens correction is used in specialized cases to provide corneal protection with the soft lens and optical correction with a rigid gas-permeable lens. Controlling the position and amount of movement of the RGP lens over the soft lens is a critical factor in fitting the piggyback system. METHODS: The movement of rigid gas-permeable lenses as part of a piggyback system was investigated under two different conditions. The RGP lens was placed on a smooth-surface soft lens and compared to a RGP lens placed on a dot matrix designed front-surface soft lens. RESULTS: When placed over a dot matrix front-surface soft lens, the RGP lens moved significantly less than when placed on the front surface of a smooth-surface soft lens. CONCLUSIONS: This controlled movement can increase patient comfort and reduce RGP slippage and lens dislocation when the piggyback lens system is prescribed.

Contact lenses for children.

Contact lenses for children are used to correct a variety of conditions. This paper reviews fitting of soft, silicone elastimer, and rigid gas-permeable contact lenses for therapeutic treatment of aphakia, anisometropia, myopia, hyperopia, esotropia, irregular astigmatism, and nystagmus. Cosmetic custom designs are described for the treatment of aniridia, albinism, amblyopia, and corneal disfigurement. Working with children and gaining their trust requires inventiveness and patience. Prescribing contact lenses for them requires developing good cooperation between the child, the parents, and the practitioner. The rewards of contact lenses wear for the appropriate pediatric patients include improving not only their vision but also their quality of life.

Disposable lenses and the marginal dry eye patient.

BACKGROUND: The patient with marginal dry eye can experience difficulty wearing soft contact lenses. Various lens types have been prescribed for the marginal dry eye patient. The introduction of disposable soft lenses adds another lens type that may be useful for this patient population. METHODS: This double-blind pilot study involved 10 subjects. The marginal dry eye subjects were fit with thin (0.07 mm at -3.00) and standard (0.105mm at -3.00 thickness), high water content (58 percent) disposable soft contact lenses. The lens type was alternated on a weekly basis for 3 weeks. Patient preference regarding acuity, comfort, and overall impression was determined. Corneal response was also evaluated. RESULTS: If there was a preference, the marginal dry eye subjects preferred the thinner lens, which also produced the least adverse corneal response. The average daily wearing time was 9 hours, and lens lubricants were used an average of three times per wearing period. CONCLUSIONS: This pilot study indicates that high water content, disposable soft lenses used on a daily wear basis can be worn by the marginal dry eye patient. Although individual variation exists, the thinner lens design was more readily accepted.
