Extended Wear and Special Contact Lenses
Though most of the patients use contact 1enses as a substitute for glasses, contact 1enses have a number of other uses also 1ike cosmetic masking of disfigured eyes, changing the colour of the eyes and balancing vision between two eyes with very different numbers. Numerous colours like blue, green, hazel etc are available in either single or mixed shades and with or without correcting number. Other medical reasons for using contact lenses include dry eyes, colour vision defects, amblyopia (lazy eye), certain cases of squint, keratoconus (conica1 cornea), cornea 1 burns or ulcers, after corneal grafting etc. Extended wear contact lenses of both GP or Soft type are available now which can even be worn while sleeping. Extended wear contact lenses should be used only by those patients who have a compelling occupational reason, medical problem or a physical disability which limits daily lens care, since these lenses are more prone to infection and other problems.
Myths and Misconceptions
The reduction of number by use of contact 1enses
(Orthokeratology) is possible in a limited number of patients but since is almost impossible to predict beforehand as to who will benefit from this; it should normally not be the only reason to go in for 'Contacts'. Another frequent misconception is that a displaced contact 1ens can get lost inside the eye. This is almost next to impossible except in cases of severe perforating eye injury. In most circumstances contact 1enses may in fact save the eye from minor injury by acting as a cover on the eye.
Though Lasers & Refractive Corneal Surgery (Myopia Surgery. Astigmatic or Hyperopia Surgery. Excimer Laser. Bladeless LASIK) have coming up well as yet another alternative to glasses, contact lenses will continue to shine like a jewel in the eye.
