Welcome to DR WILLIAM BOOTHE
Orthokeratology is the use of rigid gas-permeable contact lenses, normally worn only at night, to improve vision through the reshaping of the cornea. This method can be used as an alternative to eyeglasses, refractive surgery, or for those who prefer not to wear contact lenses during the day (for example, because lenses may become dislodged during sport.).The procedure was first used over 40 years ago when eye doctors noticed that some contact lens wearers' vision improved after wearing their lenses. A series of lenses were needed, each lens flattening the cornea a small amount until the desired results were attained. People are best suited for ORHTO-K are of any age with nearsightedness less than -4.00 diopters and astigmatism less than -1.50 diopters. There are some candidates that are not suitable for ortho-k and its best to consult your eye doctor.
A Rarer Condition: Pathologic Myopia
Physiological myopia is the most common eye disorder worldwide. A <6.00D optical aberration brought about by either increased ocular power (cornea and lens) or increased axial length is considered a normal biologic variation. Pathological myopia involves structural alterations to the globe, which may threaten sight and ocular health.Pathologic myopia and AMD may look similar, however, AMD is characterized by drusen and lacks significant peripapillary atrophy. In addition, patients with pathologic myopia are likely to be younger and have higher myopia.
