Understanding CLEAR Laser Eye Surgery
What Is CLEAR Surgery?
CLEAR (Corneal Lenticule Extraction for Advanced Refractive Correction) is a next-generation flapless laser eye surgery that corrects refractive errors by reshaping the cornea. Unlike traditional LASIK, CLEAR refractive surgery does not require creating a corneal flap or using an excimer laser. Instead, it uses the advanced Ziemer FEMTO LDV Z8 femtosecond laser to create a tiny lens-shaped piece of tissue (called a lenticule) within the cornea, which is gently removed through a small 2–3 mm micro-incision.
This minimally invasive Corneal Lenticule Extraction procedure preserves more of the cornea’s natural structure, helping maintain corneal strength while providing precise and long-lasting CLEAR vision correction. Patients can typically expect quick visual recovery, minimal discomfort, and reduced risk of flap-related complications.
What Does CLEAR Treat?
CLEAR laser eye surgery is designed to correct common refractive errors that prevent light from focusing accurately on the retina. It is primarily recommended for individuals with myopia (nearsightedness) and can also effectively treat astigmatism, reducing or eliminating dependence on glasses and contact lenses.
Using advanced Corneal Lenticule Extraction technology, CLEAR vision correction precisely reshapes the cornea to restore sharper, clearer distance vision while preserving its natural strength. The result is high-quality visual outcomes with minimal disruption to the eye’s surface and a faster recovery for most patients.
Who Is Suitable For CLEAR Surgery?
CLEAR eye treatment is ideal for individuals who want to reduce or eliminate their dependence on glasses or contact lenses. While the procedure is highly advanced, suitability depends on a comprehensive eye examination performed by an experienced eye specialist. You may be a suitable candidate for CLEAR refractive surgery if you:
- Are 18 years or older with a stable spectacle or contact lens prescription.
- Have myopia (nearsightedness) up to -10.00 D, with or without astigmatism up to 5.00 D (subject to clinical evaluation and regional approvals).
- Have healthy corneas with adequate corneal thickness, more than 500 microns.
- Wish to enjoy greater freedom from glasses or contact lenses.
- Do not have active eye infections, progressive corneal disorders (such as keratoconus), severe dry eye disease, or uncontrolled eye conditions.
Why Choose CLEAR Laser Eye Surgery?
No Corneal Flap
Unlike traditional LASIK, CLEAR laser eye surgery does not require creating a corneal flap. Instead, a tiny lenticule is removed through a small 2–3 mm micro-incision, preserving more of the cornea’s strongest anterior layers and maintaining its natural biomechanics.
With no flap to create or reposition, the procedure eliminates flap-related complications while offering a minimally invasive approach to CLEAR vision correction. This makes it an excellent choice for patients seeking advanced flapless laser eye surgery with long-term corneal stability.
Exceptional Precision
CLEAR refractive surgery is performed using the advanced Ziemer FEMTO LDV Z8, a low-energy femtosecond laser that completes the entire procedure using a single laser platform. It creates a highly precise lenticule within the cornea, allowing accurate tissue separation while preserving surrounding healthy tissue.
This advanced technology delivers predictable corneal vision correction, helping patients achieve excellent visual outcomes with enhanced precision and consistency.
Less Dry Eyes
Since CLEAR eye treatment involves only a small incision and preserves more corneal nerves than flap-based procedures, many patients experience less disruption to the eye’s natural tear film. This helps reduce the likelihood of post-operative dry eye while supporting a more comfortable healing experience.
Most patients notice improved vision within the first few days and can return to their normal daily routine soon after surgery, following their eye specialist’s advice.
Suitable for Active Lifestyles
Whether you’re an athlete, fitness enthusiast, frequent traveller, or simply enjoy an active lifestyle, CLEAR laser eye surgery offers the confidence of a flap-free procedure. Because there is no corneal flap, there is no risk of flap displacement from accidental eye trauma after healing.
Combined with long-lasting CLEAR vision correction, the procedure allows you to enjoy greater freedom from glasses and contact lenses while embracing an active, unrestricted lifestyle.
How CLEAR Laser Eye Surgery Works
Treatment Planning
Every successful CLEAR refractive surgery begins with a detailed eye examination. Your eye specialist evaluates your spectacle power, corneal thickness, corneal topography, tear film quality, pupil size, and overall eye health to determine whether you’re a suitable candidate for CLEAR vision correction. These advanced diagnostic tests help create a personalized treatment plan, ensuring the procedure is safe, precise, and tailored to your unique eyes for optimal visual outcomes.
Lenticule Creation
Once your treatment plan is finalized, the advanced Ziemer FEMTO LDV Z8 femtosecond laser creates a thin, lens-shaped piece of tissue called a lenticule within the cornea. This highly accurate process is completed without creating a corneal flap or using an excimer laser. The laser also creates a tiny 2–3 mm micro-incision, making CLEAR laser eye surgery a truly flapless laser eye surgery that preserves more of the cornea’s natural structure.
Lenticule Removal
Through the small micro-incision, the surgeon carefully separates and removes the lenticule created inside the cornea. This precisely controlled Corneal Lenticule Extraction naturally reshapes the cornea, allowing light to focus accurately on the retina. By correcting the eye’s refractive power, CLEAR eye treatment effectively addresses myopia and astigmatism, delivering sharp, natural vision while preserving more corneal tissue and nerves than conventional flap-based procedures.
Vision Recovery
Following the procedure, the tiny incision heals naturally without stitches, allowing the cornea to recover while maintaining its structural integrity. Most patients notice a significant improvement in vision within the first few days, with visual clarity continuing to stabilize over the following weeks. With proper post-operative care and follow-up, CLEAR vision correction offers long-lasting freedom from glasses or contact lenses for suitable candidates, helping them return to their everyday activities with greater confidence.
CLEAR vs Other Vision Correction Procedures
CLEAR vs LASIK
Both CLEAR laser eye surgery and LASIK are highly effective procedures for correcting refractive errors such as myopia and astigmatism, but they use different surgical techniques. LASIK creates a thin corneal flap before reshaping the cornea with an excimer laser, whereas CLEAR refractive surgery uses Corneal Lenticule Extraction to reshape the cornea through a tiny 2–3 mm micro-incision—without creating a flap.
Why Patients Choose CLEAR
- Flap-free, minimally invasive procedure
- Better preservation of corneal biomechanics
- Lower likelihood of flap-related complications
- May reduce the incidence of post-operative dry eye
- Faster return to everyday activities for many patients
CLEAR vs PRK
Both PRK and CLEAR vision correction eliminate the need for glasses or contact lenses by reshaping the cornea. However, PRK removes the outer corneal epithelium before laser treatment, requiring a longer healing period. In contrast, CLEAR eye treatment preserves the corneal surface by creating and removing a lenticule through a small micro-incision, resulting in a more comfortable recovery for many patients.
Why Patients Choose CLEAR
- No removal of the corneal surface layer
- Reduced post-operative discomfort
- Faster visual recovery
- Lower risk of corneal haze
- Suitable for many patients seeking a minimally invasive procedure
CLEAR vs ICL
Unlike ICL, which corrects vision by implanting a Collamer lens inside the eye, CLEAR laser eye surgery permanently reshapes the cornea without placing any artificial lens in the eye. Both procedures deliver excellent visual outcomes, but they are recommended for different patient profiles depending on factors such as refractive error, corneal thickness, and overall eye health.
Why Patients Choose CLEAR
- No implanted lens inside the eye
- No long-term implant maintenance
- Permanent reshaping of the cornea
- Excellent option for eligible patients with myopia and astigmatism
CLEAR vs SMILE & SILK
CLEAR, SMILE, and SILK represent the latest generation of flapless laser eye surgery, all based on the principle of Corneal Lenticule Extraction. The primary difference lies in the laser platform and technology used. CLEAR laser eye surgery is performed using the Ziemer FEMTO LDV Z8, while SMILE uses the ZEISS VisuMax platform and SILK is performed using the Johnson & Johnson ELITA system. Each technology offers precise corneal vision correction, and the most suitable procedure depends on your eye health, prescription, and your eye specialist’s clinical recommendation.
Why Patients Choose CLEAR
- Advanced low-energy femtosecond laser technology
- Preserves more corneal nerves and biomechanics
The Science Behind CLEAR Eye Surgery
Innovation Behind Every Clearer View
Low-Energy Laser
Unlike conventional laser systems that rely on higher-energy pulses, the Ziemer FEMTO LDV Z8 uses low-energy, high-frequency femtosecond laser pulses to create the lenticule with exceptional precision. This gentle laser-tissue interaction minimizes collateral impact on the surrounding corneal tissue, supporting smoother healing and preserving the eye’s natural anatomy.
High-Frequency Precision
The laser delivers thousands of precisely controlled femtosecond pulses in rapid succession, allowing highly accurate Corneal Lenticule Extraction. This high-frequency performance helps create smooth tissue planes, improves surgical precision, and contributes to predictable CLEAR vision correction outcomes tailored to each patient’s prescription.
Intelligent Corneal Docking
The Ziemer FEMTO LDV Z8 features an advanced docking system that stabilizes the eye gently during the procedure while maintaining optimal alignment throughout treatment. This controlled positioning enhances surgical accuracy, improves patient comfort, and allows the laser to deliver highly consistent corneal vision correction with exceptional precision.
Single-Laser Module
CLEAR refractive surgery is completed using a single femtosecond laser platform that creates both the lenticule and the tiny 2–3 mm micro-incision without requiring a corneal flap or an excimer laser. This streamlined, minimally invasive approach preserves more of the cornea’s natural strength while delivering precise, long-lasting vision correction with a comfortable recovery experience.
Cost of CLEAR Eye Surgery
The cost of CLEAR Surgery can vary depending on several factors, including the clinic, surgeon’s experience, and geographic location. At Centre For Sight, it starts at an affordable price for both eyes. It is essential to discuss the costs and available payment plans during the consultation to make an informed decision.
Potential Risks & Complications of CLEAR Surgery
- Temporary Blurred Vision
Mild fluctuations or hazy vision may occur during the initial healing phase and usually improve as the cornea stabilizes.
- Dry Eye Symptoms
Some patients may experience temporary dryness or irritation after CLEAR refractive surgery. Prescribed lubricating eye drops typically help relieve these symptoms.
- Glare, Halos & Light Sensitivity
Temporary glare, halos around lights, or increased sensitivity to bright light may occur, particularly at night, but generally reduce as healing progresses.
