CLEAR: Corneal Lenticule Extraction for Advanced Refractive Correction
CLEAR (Corneal Lenticule Extraction for Advanced Refractive Correction) is a groundbreaking KLex ( Kerato-lenticule extraction) procedure designed for the precise treatment of myopia and astigmatism. This innovative technique is integrated into the new FEMTO LDV Z8 laser system, ensuring exceptional precision and safety.
The Low Energy Concept: A Key Advantage
One of the standout features of the CLEAR procedure is the Low Energy Concept. Ziemer is known for inventing the concept of low energy femtosecond laser. This approach minimizes tissue damage and the inflammatory response, which promotes faster visual recovery. The low energy levels used during the procedure result in less disruption to the corneal structure, reducing post-operative complications and enhancing patient outcomes. In 2014, a study done to evaluate the tissue damage and cell death due to femtosecond laser revealed that corneal cell death was largely absent when using the low energy laser of Femto LDV when compared to the VisuMax platform which caused cell death.

Special Features of CLEAR
The Ziemer laser systems, integral to the CLEAR procedure, offer several advanced features:
01.
Visual axis centration and Repositioning
The system allows for easy centration on the eye with options to reposition the lenticule under suction, ensuring precise alignment and centration on the visual axis.
02.
Cyclotorsion Compensation
Using the latest generation AI Engine, the system automatically detects the cylindrical axis of the eye after docking and repositions the lenticule to compensate for any cyclotorsion resulting in accurate correction of astigmatism. Following the innovations of Ziemer and introduction of these features in CLEAR , cyclotorsion compensation and visual axis centration are now included as standard features on other KLex platforms ; often described in commonplace with the suffix “PRO” such as SMILE PRO and CLEAR PRO .
03.
iOCT guided treatment
Another unique feature of the CLEAR platform is the integration of Optical Coherence Tomography within the machine. Hence, during the procedure of CLEAR, the lenticule is clearly visualized by the surgeon using cross-sectional real-time imaging before application of the lenticule cuts. This adds another layer of safety and allows maximum precision in lenticule extraction surgery.
04.
Low Energy Concept
By using low energy during the procedure, the laser minimizes tissue damage and inflammation, leading to quickest recovery times and better visual outcomes. To know more , click here. ( https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7912418/)
05.
Guiding Tunnels and Multi Incisions
These features, unique to CLEAR, facilitate easy lenticule separation with customizable incision options, providing flexibility and accuracy. This feature is unique to the CLEAR platform.
Pioneering Next generation of KLex
For the various inventions and innovations introduced in the Femto LDV Z8 system , the CLEAR ® procedure is widely regarded as the leader of next generation kerato-lenticule extraction procedures. Before the introduction of CLEAR ® in 2019 , KLex was performed with high energy lasers with non-overlapping laser spots and no control over cyclotorsion. Moreover, visual axis centration was also not possible.
CLEAR ® ushered the generation change in KLex procedures and has been instrumental in the upgradation of KLex technology. The clinical success of CLEAR ® has pushed refractive surgery towards the era of next generation lenticule procedures , namely , CLEAR ® , SMILE PRO ® , SiLK ® and SmartSight ® .
Immediate Recovery Coupled with Ultimate Safety
The CLEAR ® procedure stands out from its predecessors because of its quick recovery and superior post-surgery comfort. Imagine undergoing an eye surgery today and seamlessly transitioning back to your daily life tomorrow! The flapless nature of the CLEAR ® Procedure further enhances its safety quotient, positioning it as a leading choice among modern spectacle removal surgeries.
Bladeless, Painless, and Flapless : The Future is here
CLEAR stands as a beacon of modern medical innovation by delivering a bladeless, painless and flapless experience. Eliminating the discomfort often linked with injections, the procedure employs eye drops for numbing. Within a concise span of 10 minutes, a lenticule of corneal tissue is crafted using advanced laser technology and subsequently removed through a micro opening which seals within hours. It leaves your eye as safe as it was never touched .
The Sophistication of the Femto LDV Z8 Laser Machine
Central to the CLEAR procedure’s success is the sophisticated Femto LDV Z8 Laser Machine. With an ergonomic handpiece and patient interface , it keeps patients’ comfort and surgical experience at its centrepoint. This, coupled with unmatched accuracy and precision makes CLEAR ® the obvious choice for your spectacle removal .
Addressing the Concern of Dry Eyes
A common post-operative issue in many eye surgeries is the onset of dry eyes. However, with the CLEAR procedure, this concern sees a significant reduction, further amplifying its esteemed position in the field.
CLEAR Eye Surgery Cost in India
The cost of CLEAR eye surgery ranges between Rs 1,00,000-1,30,000 in India, for both the eyes. It can vary depending upon the hospital and the surgeon.
Frequently Asked Questions
1. What is the CLEAR Procedure?
The CLEAR Procedure, also known as Kerato-Lenticule Extraction (KLex), is a state-of-the-art laser vision correction technique. It is the most advanced flap-free laser procedure available today, designed to correct nearsightedness (myopia) up to -10D and astigmatism up to -5D, making it a highly versatile option.
2. How does the CLEAR Procedure work?
Utilizing low-energy femtosecond laser technology, the CLEAR Procedure corrects refractive errors by creating a thin, disc-shaped tissue layer (lenticule) within the cornea that corresponds to the patient’s prescription. This lenticule is then carefully removed, reshaping the cornea and enhancing visual clarity.
