INSERT SOFT CONTACT LENS
There are different ways of inserting soft contact lens (CL):
1. Wet the tip of right index finger. Put soft contact lens on finger tip.Pull the upper eyelid of right eye with other hand and lower eyelid with middle finger of right hand. Put contact lens by looking directly on to the contact lens.
Fitting Technique
1. Ask the patient to wash her hands and eyes with soap and water. Shake excess water.
2. Take contact lens and check inside out and right left.
3. Wet contact lens should be put on finger and introduced in the eye. Ask the patient to move her eyeball so that the lens settles on cornea.
4. If patient experiences foreign body sensation ask her to close the eyes for 15-30 minutes.
5. Do slit-lamp examination for type of fitting. Base curve of contact lens or diameter of contact lens can be adjusted to achieve alignment fitting. Following points should be looked for:
a. Centration: Contact lens should be nicely centered on cornea. Cornea should be properly covered by contact lens
b. Movements of contact lens: With each blink contact lens should move 0.5-1.00 mm, lesser movements indicate steep fit and greater movements indicate flat fit.
6. In semisoft and hard contact lens fitting, fluorescein stain is used. By this method pooling of dye (Green area) and corneal touch (Blue area) can be easily appreciated.
