Name of the Procedure:

Lenticular Lens Implantation (Single Lens)

• Common name: Implantable Contact Lens (ICL)
• Technical term: Lenticular Lens, per lens, single (HCPCS Code: V2121)

Summary

Lenticular Lens Implantation is a surgical procedure where a specialized plastic or silicone lens is implanted into the eye to help improve vision. This typically involves placing the lens either in front of or behind the iris (the colored part of the eye).

Purpose

This procedure aims to correct refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), or astigmatism. The primary goal is to enhance visual clarity and reduce the need for eyeglasses or contact lenses.

Indications

• Severe myopia, hyperopia, or astigmatism that is not adequately corrected by standard eyewear
• Patients who are not suitable candidates for laser eye surgery (LASIK/PRK)
• Individuals seeking a permanent solution for vision correction

Preparation

• Comprehensive eye examination and measurement
• Discontinuation of contact lens use several days before the procedure
• Preoperative instructions may include fasting and avoiding certain medications (as directed by the surgeon)

Procedure Description

1. The surgeon administers local anesthesia to numb the eye.
2. A small incision is made in the cornea.
3. The lenticular lens is carefully inserted through the incision.
4. The lens is positioned either in front of or behind the iris, depending on the type of implant.
5. The incision is then closed, often self-sealing and not requiring stitches.

Tools:

• Micro-surgical instruments
• Implantable lens (ICL)

Anesthesia:

• Local anesthesia is typically used, with possible mild sedation.

Duration

The procedure usually takes about 15-30 minutes per eye.

Setting

The procedure is usually performed in an outpatient clinic or an ambulatory surgical center.

Personnel

• Ophthalmic surgeon
• Nurse or surgical technician
• Anesthesiologist (if sedation is used)

Risks and Complications

• Common risks: Infection, inflammation, increased intraocular pressure
• Rare risks: Lens dislocation, cataract formation, retinal detachment
• Management: Immediate medical attention for complications

Benefits

• Significant improvement in vision
• Reduced dependence on eyeglasses or contact lenses
• Immediate vision improvement within a few days

Recovery

• Use prescribed eye drops to prevent infection and reduce inflammation
• Avoid strenuous activities for a few weeks
• Regular follow-up appointments to monitor healing
• Most patients resume daily activities within a week

Alternatives

• Eyeglasses or contact lenses: Non-surgical options with less risk but requiring continuous use
• LASIK or PRK: Laser surgery options for vision correction with different risk profiles
• Pros and Cons:
  • Glasses/Contacts: Non-invasive but inconvenient
  • LASIK/PRK: Permanent correction but not suitable for everyone

Patient Experience

During:

• Minimal discomfort due to local anesthesia
• Possible sensation of pressure or light manipulation

After:

• Mild discomfort or irritation for a few days
• Prescribed pain management if necessary
• Improved vision typically within a few days, though full stabilization may take a few weeks
