Ways to treat Dry eye:
A trial of Artificial tears is simple and effective in relieving the
symptoms, though not the basic illness.
A host of Tears substitutes are available in the market.
They contain -
| Methyl cellulose and its derivatives e.g. Tears Naturale. |
| Polyvinyl alcohol e.g. Hypotears. |
| Preservative |
Preservative free tears are advocated mainly for those with allergies
,though they can be used by others too. They may be more expensive.
Applying Lubricating ointment at night helps.
Occlusion of the lacrimal punctum with Silicon
Punctal Plugs. This decreases the drainage of tears and keeps the eye
wet, thus conserves tears. The Silicon Plugs are tiny, shaped like a
double arrow and do not cause any irritation to the eye. They can be
removed and inserted with ease, by the eye-doctor, in the office.
A permanent treatment of dry eye is Punctal
Occlusion (Blockade). This means the lacrimal punctum is blocked by using
Laser Burn or with heat Cautery. It is not done very frequently but is of
great help in cases of severe dry eye.
