Lenticule Surgery (SMILE / CLEAR)
Lenticule surgery is a modern form of laser eye surgery that corrects vision by reshaping the cornea using a precise femtosecond laser. Instead of removing corneal tissue with an excimer laser, a small disc of tissue (called a lenticule) is created within the cornea and gently removed through a tiny opening. This approach allows vision to be corrected with minimal disturbance to the surface of the eye. CLEAR® and SMILE® are both advanced lenticule-based procedures designed to treat short-sightedness and astigmatism while preserving corneal strength and supporting a comfortable recovery for eligible patients.
What is CLEAR Lenticule Surgery?
CLEAR® (Corneal Lenticule Extraction for Advanced Refractive Correction) is considered third-generation laser eye surgery, representing the latest evolution in laser vision correction after LASIK and SMILE®. Like other lenticule-based procedures, it corrects short-sightedness (myopia) and astigmatism by using a femtosecond laser to create a thin, lens-shaped piece of tissue (the lenticule) within the cornea, which is then removed through a very small incision. This reshapes the cornea and improves how light is focused onto the retina, helping to achieve clearer vision.
CLEAR® is performed using advanced low-energy femtosecond laser technology and does not require the creation of a large corneal flap. This approach is designed to preserve corneal strength and reduce disruption to the eye’s surface, which may support comfort and healing in suitable patients. Compared with SMILE®, CLEAR® offers enhanced eye-tracking and alignment features, very low laser energy delivery, and greater flexibility in treatment planning. These advances are intended to improve precision and consistency, particularly for patients with astigmatism. As with all laser eye surgery, suitability for CLEAR® is determined through a detailed clinical assessment, ensuring the procedure is appropriate, safe, and tailored to each patient’s eyes.
CLEAR / SMILE Eye Surgery
CLEAR® is a third-generation lenticule laser eye surgery that uses a single femtosecond laser to correct short-sightedness and astigmatism without the need for a corneal flap. The procedure typically takes only a few minutes per eye, with the laser itself operating for less than 30 seconds, and is performed through a very small incision to minimise disruption to the corneal surface. LaserVision was the first clinic in the UK to introduce the Z8 femtosecond laser and CLEAR® surgical technology, bringing the latest generation of lenticule surgery to eligible patients. Many patients experience functional vision improvement within days, with vision continuing to stabilise over the following weeks, following a comprehensive assessment to confirm suitability and safety.

How is CLEAR surgery performed?
- 1.Local anaesthetic eye drops are applied to both eyes
- 2.The Ziemer Z8 laser directs a series of pulses at the cornea
- 3.These pulses form bubbles which outline a small clear lens (lenticule)
- 4. The laser then produces a small tunnel in the cornea from which the lenticule can be removed
- 5.There is no flap and no requirement for stitches as the small tunnel is millimetres wide and self healing
