Scleral Fixation
Scleral Fixation Surgery: Advanced Intraocular Lens Implantation for Complex Cases
Scleral Fixation is an advanced ophthalmic surgical technique used in patients who lack adequate capsular support for standard intraocular lens implantation. The procedure is commonly performed in complex cataract surgery cases, lens dislocation, ocular trauma, or other conditions affecting the natural stability of the intraocular lens.
At Özel Sistem Eye Medical Center, scleral fixation procedures are performed by our experienced vitreoretinal and anterior segment surgery team using modern microsurgical techniques and advanced intraocular lens fixation methods.
What is Scleral Fixation?
Under normal conditions, an intraocular lens (IOL) is placed within the natural capsular bag of the eye during cataract surgery. However, in some patients, this support structure may be absent or insufficient.
Scleral Fixation is a surgical method in which the intraocular lens is secured to the sclera, the white outer wall of the eye, allowing stable lens positioning when standard lens implantation is not possible.
The procedure may be performed using either sutured or sutureless fixation techniques depending on the patient's ocular anatomy and surgical requirements.
When is Scleral Fixation Required?
Scleral fixation may be recommended in cases such as:
- Inadequate capsular support after complicated cataract surgery
- Dislocation or instability of an intraocular lens
- Ocular trauma causing zonular damage
- Congenital lens instability syndromes such as ectopia lentis
- Aphakia (absence of the natural or artificial lens)
- Complex intraocular lens exchange procedures
A comprehensive ophthalmic and retinal evaluation is essential before surgery.
Who is a Suitable Candidate?
Scleral fixation surgery may be suitable for:
- Patients without sufficient capsular support
- Individuals with displaced or unstable intraocular lenses
- Patients requiring advanced secondary intraocular lens implantation
- Selected aphakic patients unable to tolerate high-powered glasses or contact lenses
Each case requires individualized surgical planning based on ocular structure and retinal health.
How is Scleral Fixation Surgery Performed?
The procedure is typically performed under local or general anesthesia in a sterile operating room environment.
Depending on the clinical situation, surgery may include:
- Vitrectomy surgery when necessary
- Placement of a specialized intraocular lens
- Scleral fixation of the lens using sutured or sutureless techniques
- Stabilization of the lens within the visual axis
Modern sutureless fixation techniques may offer improved surgical efficiency and reduced suture-related complications in selected patients.
Recovery After Surgery
Recovery after scleral fixation surgery may take longer than standard cataract surgery due to the complexity of the procedure.
Temporary redness, blurred vision, mild discomfort, and ocular irritation may occur during the early postoperative period.
Visual recovery generally progresses gradually over the following weeks, while regular postoperative monitoring and prescribed medications remain essential for optimal healing.
Possible Risks and Considerations
As with all intraocular surgeries, scleral fixation carries certain risks, particularly in complex ocular conditions.
Potential risks may include:
- Elevated intraocular pressure
- Lens decentration or tilt
- Retinal complications
- Intraocular inflammation
- Infection or bleeding
- Suture-related complications in selected techniques
Careful surgical planning and experienced surgical management are essential for successful outcomes.
When Should You Consult an Ophthalmologist?
Professional evaluation is recommended if you experience:
- Sudden visual deterioration after cataract surgery
- Sensation of lens movement inside the eye
- Eye trauma with visual changes
- Severe blurred vision or visual distortion
- Persistent eye discomfort after intraocular surgery
