Name of the Procedure:

Replacement of Contact Lens

Summary

Replacing a contact lens involves the removal of the current contact lens and inserting a new one. This is typically done by the patient themselves or with assistance from an eye care professional.

Purpose

Replacing contact lenses is necessary to maintain eye health and ensure clear vision. It addresses issues such as discomfort, dryness, or blurry vision associated with worn or damaged lenses.

Indications

• Blurry vision
• Discomfort or dryness in the eyes
• Visible damage or defects on the contact lens
• Replacement schedule according to lens type (daily, bi-weekly, monthly)

Preparation

• Wash and dry hands thoroughly before handling contact lenses.
• Gather necessary supplies: new contact lenses, saline or contact lens solution, and a clean lens case.
• If wearing makeup, remove it before handling the lenses.

Procedure Description

1. Remove the old lens:
   • Look up and use the middle finger to pull down the lower eyelid.
   • Use the index finger and thumb to gently pinch the lens and remove it.
2. Clean the lens case:
   • Rinse the case with fresh contact lens solution and let it air dry.
3. Insert the new lens:
   • Place the new lens on the tip of the index finger.
   • Ensure the lens is not inside out.
   • Look up and pull down the lower eyelid with the middle finger.
   • Gently place the lens on the cornea.
   • Blink a few times to ensure the lens is in place.

No anesthesia or sedation is required.

Duration

The entire process typically takes 5-10 minutes.

Setting

Home, though it can be performed at an optometrist's office if assistance is needed.

Personnel

Primarily self-performed. An optometrist or ophthalmologist can assist if necessary.

Risks and Complications

• Mild discomfort or irritation
• Risk of infection if hands or lenses are not clean
• Potential for scratching the cornea if not done properly

Benefits

• Improved vision and comfort
• Reduced risk of eye infections with proper hygiene
• Enhanced convenience compared to glasses for some activities

Recovery

• No significant recovery period is needed.
• Follow-up appointments with an eye care professional as recommended, typically annually.

Alternatives

• Eyeglasses: non-invasive, but may not be as convenient for all activities.

• Surgical options like LASIK for longer-term vision correction.

  Pros of alternatives:

  • Glasses are easy to put on and remove, minimal maintenance.

  • LASIK offers long-term correction with no need for daily wear.

    Cons of alternatives:

  • Glasses can be cumbersome and affected by weather conditions.
  • LASIK involves surgical risks and costs.

Patient Experience

• The patient may feel a slight sensation when inserting or removing the lens.
• Mild discomfort is normal initially but should subside quickly.
• Using rewetting drops can enhance comfort during wear.
• If pain or significant discomfort persists, consult an eye care professional.
