Vision correction has evolved significantly, offering patients multiple options beyond traditional glasses and contact lenses. Among the advanced solutions available today, Intacs eye surgery and implanted contact lenses (ICLs) are two of the most effective methods for treating specific vision problems. These procedures provide long-term improvements for people suffering from keratoconus, high myopia, or other refractive errors.
If you are exploring alternatives to LASIK or PRK, this guide will provide an in-depth understanding of Intacs eye surgery and implanted contact lenses, their benefits, risks, the recovery process, and how they compare in helping you achieve better vision.
Understanding Intacs Eye Surgery
What Is Intacs Eye Surgery?
Intacs eye surgery is a minimally invasive corneal implant procedure designed primarily to treat keratoconus and mild refractive errors. It involves the insertion of thin, semi-circular plastic rings into the cornea to reshape its structure and improve visual clarity.
Keratoconus is a progressive eye condition where the cornea thins and bulges into a cone shape, causing distorted vision. Intacs eye surgery helps flatten the cornea and stabilize its shape, often delaying or eliminating the need for a corneal transplant.
How Intacs Work
Intacs are small, clear plastic ring segments made of biocompatible materials. Once implanted into the cornea, they function as a supportive framework, reducing corneal irregularities and improving vision clarity. Unlike LASIK, which removes corneal tissue, Intacs eye surgery simply reshapes the cornea without permanent alterations.
Who Is a Candidate for Intacs Eye Surgery?
Intacs eye surgery is suitable for individuals who:
Have mild to moderate keratoconus
Experience progressive vision deterioration due to corneal irregularities
Are not eligible for LASIK or PRK due to corneal thinning
Want a reversible and minimally invasive vision correction solution
Prefer to avoid corneal transplant surgery
Procedure for Intacs Eye Surgery
Pre-Surgical Examination – A comprehensive eye exam is conducted to assess corneal thickness, shape, and overall eye health.
Anesthesia and Incision – Numbing eye drops are applied, and a small incision is made in the cornea.
Insertion of Intacs – The surgeon places the Intacs segments within the corneal stroma to reshape the cornea.
Closure and Recovery – The procedure takes about 15-30 minutes, and patients can return home the same day.
Benefits of Intacs Eye Surgery
Reduces corneal irregularities, improving vision clarity
Slows or halts keratoconus progression
Reversible and removable, if necessary
Preserves corneal tissue, making it a safer alternative to LASIK for keratoconus patients
Minimal downtime, with many patients resuming normal activities within days
Potential Risks and Side Effects
While generally safe, Intacs eye surgery carries some risks, including:
- Glare or halos at night
- Infection or corneal irritation (rare)
- Foreign body sensation during the healing process
- Limited vision improvement in advanced keratoconus cases
For patients requiring further vision correction beyond Intacs eye surgery, implanted contact lenses may be a viable additional solution.
Understanding Implanted Contact Lenses (ICLs)
What Are Implanted Contact Lenses?
Implanted contact lenses (ICLs), also known as phakic intraocular lenses (pIOLs), are artificial lenses surgically placed inside the eye to correct severe myopia, hyperopia, and astigmatism. Unlike traditional contact lenses that sit on the cornea’s surface, ICLs are implanted between the natural lens and iris for long-term vision correction.
How Implanted Contact Lenses Work
ICLs function similarly to permanent contact lenses, enhancing vision without altering corneal tissue. Unlike LASIK, which reshapes the cornea to correct vision, ICLs work in conjunction with the eye’s natural lens, allowing for clearer and sharper vision.
Who Is a Candidate for Implanted Contact Lenses?
Implanted contact lenses are ideal for individuals who:
Have high myopia (-3.00D to -20.00D) or hyperopia
Are not good candidates for LASIK due to thin corneas
Want a reversible vision correction option
Have a stable vision prescription for at least a year
Prefer a high-definition vision solution
Procedure for Implanted Contact Lenses
Eye Examination and Measurements – The surgeon determines the correct lens power and size.
Anesthesia and Small Incision – A tiny opening is created in the cornea using local anesthesia.
ICL Implantation – The lens is folded and inserted through the incision, then positioned behind the iris.
Recovery and Post-Op Care – Most patients experience improved vision within 24-48 hours, with full stabilization in a few weeks.
Benefits of Implanted Contact Lenses
Provides sharper, high-definition vision compared to LASIK
No corneal tissue removal, making it a safer alternative for thin corneas
Built-in UV protection for long-term eye health
Reversible and removable if needed
Quick recovery—most patients resume normal activities within a few days
Potential Risks and Side Effects
While ICLs are highly safe, possible risks include:
Slight increase in intraocular pressure (IOP), which may lead to glaucoma if untreated
Rare cases of cataract formation over time
Temporary night glare or halos
Which Procedure Is Right for You?
If you have keratoconus, Intacs eye surgery is the better option.
If you want permanent vision correction without corneal changes, implanted contact lenses are ideal.
If you have both keratoconus and high myopia, you may require a combination of Intacs and ICLs for optimal results.
Post-Procedure Care and Recovery Tips
Regardless of whether you undergo Intacs eye surgery or receive implanted contact lenses, following proper post-op care is essential for smooth recovery and optimal vision outcomes.
Post-Op Care Tips
Use prescribed eye drops to prevent infection and reduce inflammation.
Avoid rubbing your eyes for at least two weeks after surgery.
Wear protective eyewear during sleep and outdoor activities.
Attend all follow-up appointments to monitor healing and eye health.
Limit screen time and exposure to bright lights during the initial recovery phase.
