These contact lenses are made of a soft, flexible plastic, used for correction of hyperopia, myopia, astigmatism and aphakia. Generally, most patients adapt to soft lenses quickly.

Insertion of the soft lenses

·         Arrange all items you will need.

·         Wash your hands carefully with a non-perfumed, non-oil base soap and clean tap water. Thoroughly dry your hands to remove all water.

·         Remove the contact lens from the case.

·         Rinse the lens with rinsing solution.

·         Place the lens on the tip of the index finger of the inserting hand, and check for lint, debris, or torn edges.

·         Check if the lens is correctly oriented by one of the following two methods:

A.   Place the lens on the tip of the dry index finger you will notice "Outside out, inside in," lens edges sweep upward (Correct). As shown in when the lens is oriented.

B.   Inside out, outside in," lens edges flare outward (Incorrect).

·         Place the lens on the tip of the index finger of the inserting hand, Place 1 or 2 drops of solution in the centre of the lens.

·         Place the index finger of your free hand close to the lashes of the upper eyelid and gently pull up. Place the middle finger of the inserting hand close to the lashes of the lower eyelid and gently pull down, exposing the cornea.

·         Look straight ahead into your mirror with both eyes open. Then place the lens on the cornea gently until it settles in its place.

·         Release your eyelids and close the eye for a few seconds. This will help centre the lens on the cornea

·         Rinse your lens case with solution and let it air dry.

·         Insert the right lens first to avoid mixing the right with the left.

Removing the Lenses

·         Wash your hands with a non-perfumed, non-oil base soap and clean tap water. Dry them carefully to remove all water.

·         Gently touch the contact lens with the index finger and slide it slightly down.

·         Look up and lightly pinch the lens between your thumb and index finger to remove it. Do so with the pads of your fingers, not your fingernails.

·         Always remove the right lens first so as not to mix up the two lenses.

Cleaning and Disinfecting the Contact Lenses

·         Wash your hands with a non-perfumed, non-oil base soap and clean tap water. Dry them thoroughly to remove all water.

·         Place the lens in the palm of your hand and put a few drops of solution in the centre of the lens.

·         Gently rub the lens with a back-and-forth or circular motion with the pad of your index finger or thumb for 30 seconds so that the front and back surfaces of the lens are cleaned.

·         Rinse generously with solution (do not use tap water for rinsing).

·         Fill the case with solution to cover the lenses and leave them overnight, so they are ready to wear again.

Wearing Schedule

 First day start with 4 hours and increase time by 2 hours daily until you reach 12 hours per day. Do not exceed 12 hours until your next appointment with the optometrist.

Corneal Transplantation

It is surgical procedure where an ophthalmologist, changes a cornea with a new one by donor and fix with tiny surgical stitches.

 Causes of corneal transplantation

·        Keratoconus, which is diseases, that increases gradually thinning of the cornea resulting blurry vision.

·        Hereditary corneal diseases.

·        Corneal infections that not responded to treatment.

·        Corneal ulcer.

·        Severe corneal injuries that caused corneal opacity.

·        Corneal burns.

·        Complications after eye surgeries like cataract or glaucoma.

 Corneal transplant Types:

Penetrating keratoplasty: in this procedure, the surgeon removes all the corneal layers, replaced with donor’s ones, and fixes it with sutures.

Lamellar keratoplasty: In this procedure, the surgeon replaces all the damaged corneal layers with healthy donor ones and fix by stitches.

Descemet’s Stripping Endothelial keratoplasty (DSAEK): in which the inner layer of cornea is removed, and replaced with tissue but attached to the cornea with gas or air instead of stitches.

Corneal Rejection

Corneal rejection been expected at any time and this requires emergency admission in hospital, so if you have any of the following signs you should seek medical assistance directly:

o   Decrease in visual acuity.

o   Redness.

o   Foreign body sensation.

o   Tearing

o   Photophobia.

o   Pain.

Early diagnosis helps much in the successful treatment of corneal rejection. Usually, the physician prescribes certain medications to help your body accept the corneal graft.
