Secondary Intraocular Lens Applications (Scleral-Sutured)

The human eye is built upon a foundation of perfect anatomical balance and engineering. Our natural intraocular lens, which enables clear vision by refracting incoming light, hangs in the center of the eye supported by invisible fibers within a thin yet durable membrane (the capsule). However, this delicate balance can be disrupted due to severe eye trauma, complications from previous surgeries, or genetic syndromes; the lens or its supporting membrane can be torn, fragmented, or displaced.

In these seemingly hopeless scenarios where the eye is left "lensless" (aphakic) and vision is significantly lost, Secondary Intraocular Lens Applications (Scleral-Sutured Lenses)—one of today’s most advanced microsurgical techniques—come into play. As Ophthalmology Specialist Ayşe Öner and her clinical team, who possess international experience in complex ocular surgeries, we reconstruct the disrupted anatomy of the eye, saving our patients from a life of thick-lensed glasses or a blurred world. By combining Turkey’s leading infrastructure in global health tourism with our VIP service approach, we offer patients from around the world zero waiting times, maximum surgical safety, and a flawless healing experience.

What is a Secondary Intraocular Lens?

In a standard cataract surgery (Primary Lens Application), the opaque natural lens is cleared using ultrasonic waves, but the outer membrane (capsule) is left in place. The artificial lens is then tucked into this natural "pocket."

However, in certain cases, this natural capsule support may be entirely absent. When there is no anatomical support left to hold a lens, the procedures used are called "Secondary Intraocular Lens Applications." In such instances, the new artificial lens must be anchored directly to the sclera (the white, sturdy outer wall of the eye) to ensure it remains centered with millimeter precision. This technical and highly sensitive procedure is known as "Scleral Fixation."

Why is Capsular Support Lost?

The need for scleral fixation typically arises in complex and challenging scenarios:

1. Complicated Previous Cataract Surgeries: During a previous surgery, the natural capsule may have been torn due to a very hard cataract or inherent weakness in the eye structure, leaving the patient "aphakic" (without a lens).
2. Lens Dislocation: Years after a successful surgery, the fibers holding the artificial lens can weaken (often due to Pseudoexfoliation Syndrome), causing the lens to detach and fall into the back of the eye (vitreous cavity).
3. Severe Eye Trauma: Blunt force or penetrating injuries can suddenly snap the supporting fibers (zonules), leading to total lens displacement (luxation).
4. Genetic and Systemic Syndromes: In conditions like Marfan Syndrome or Ehlers-Danlos Syndrome, the fibers holding the lens are congenitally weak and can fail even at a young age.

Symptoms of Lens Loss or Displacement

Living without an intraocular lens or with a displaced one results in severe symptoms that can paralyze daily life:

1. Sudden, Profound Vision Loss: The world appears extremely blurred, as if looking through water.
2. High Hyperopia: A lensless eye requires very thick, heavy "bottle-bottom" glasses (typically between $+10.00$ and $+14.00$ diopters) to see.
3. Double Vision (Diplopia) and Glare: If the lens has shifted but not fallen completely, its edge interferes with the visual axis, causing light to refract twice.
4. Iris Tremors (Iridodonesis): Because the lens support is gone, the colored part of the eye (iris) shakes like jelly whenever the eye moves.

Surgical Excellence: How is Scleral Fixation Performed?

This is a reconstructive operation that requires simultaneous intervention in both the front and back segments of the eye. It should only be performed by surgeons with high-level experience in Vitreoretinal Surgery.

1. Vitrectomy: The procedure usually begins with Pars Plana Vitrectomy (PPV). Any lens fragments or the fallen lens in the back of the eye are carefully removed using microscopic tools without damaging the retina.
2. Scleral Anchoring: A new, foldable artificial lens is inserted. Its "legs" (haptics) are sutured to the white of the eye using permanent, high-strength surgical threads (like Gore-Tex or Prolene). In suitable cases, Dr. Ayşe Öner also utilizes the Yamane Technique (Sutureless Scleral Tunnel), where the haptics are secured into microscopic tunnels in the sclera without the need for threads.
3. Millimetric Centering: The lens is precisely centered behind the pupil, acting like a hammock that stays secure and stable for a lifetime.
