Name of the Procedure:

Repositioning of Intraocular Lens Prosthesis, Requiring an Incision
Common name(s): Intraocular lens repositioning, IOL repositioning

Summary

Intraocular lens (IOL) repositioning is a surgical procedure to correct the position of a previously implanted lens inside the eye. This procedure involves making an incision to access and reposition the lens to improve visual outcomes.

Purpose

The procedure addresses misalignment or displacement of the intraocular lens, which can occur after cataract surgery. The goal is to restore proper lens positioning to improve vision clarity and overall ocular health.

Indications

• Blurred vision due to lens misalignment (decent ration)
• Double vision caused by a displaced lens
• Eye pain or discomfort stemming from improper lens placement
• Previous cataract surgery with poor visual results due to lens dislocation

Preparation

• Patients may be advised to fast for several hours before the procedure.
• Adjustments to current medications, particularly blood thinners, may be necessary.
• Pre-procedure assessments could include visual acuity tests, eye measurements, and a thorough eye examination.

Procedure Description

1. The patient receives local anesthesia to numb the eye.
2. A small incision is made on the surface of the eye.
3. Specialized surgical tools are used to carefully adjust and reposition the intraocular lens.
4. The lens is securely re-fixed in the correct position within the eye.
5. The incision may be closed with tiny sutures or may heal on its own in some cases.
6. Antibiotic and anti-inflammatory eye drops may be administered to prevent infection and reduce swelling.

Duration

The procedure typically takes about 30 to 60 minutes.

Setting

The procedure is usually performed in an outpatient surgical center or a hospital.

Personnel

• Ophthalmic surgeon
• Surgical nurse
• Anesthesiologist or nurse anesthetist (if additional sedation is required)

Risks and Complications

• Infection
• Bleeding
• Increased intraocular pressure
• Retinal detachment
• Swelling or inflammation
• Vision changes or loss

Benefits

• Improved visual clarity
• Reduced eye pain and discomfort
• Better overall vision outcomes
• Enhanced quality of life

Recovery

• Patients may need to use prescribed eye drops to prevent infection and manage inflammation.
• Follow-up appointments will be scheduled to monitor healing.
• Avoid strenuous activities and heavy lifting for several weeks.
• Full recovery typically takes a few weeks, with gradual improvements in vision.

Alternatives

• Conservative management with glasses or contact lenses to correct vision.
• Replacement of the IOL if repositioning is not successful or feasible.
• Pros: Non-surgical options are less invasive and have fewer risks.
• Cons: Non-surgical options may not fully correct vision issues caused by lens displacement.

Patient Experience

During the procedure, patients should feel minimal discomfort due to local anesthesia. Post-procedure, there may be some mild pain or discomfort, which can be managed with prescribed medications. It is common to experience blurred vision initially, which should improve as the eye heals. Patients are advised to follow all recovery instructions carefully to ensure optimal healing and outcomes.
