<h2><span style="color: #00826a;">Treatment of Refractive Errors with Smart Surf (TransPRK)</span></h2>
<p>This is a treatment for myopia, hyperopia, and astigmatism without any contact with the patient&#8217;s eye. There is no suction and no use of a blade (Transepithelial photorefractive Keratectomy): “No-Touch” Treatment Technique, free from any contact with the eye at every step. There is no use of instruments to scrape the corneal surface, no locking, suction, or cutting of the cornea.</p>

<h2><span style="color: #00826a;">Treatment of Refractive Errors with Femto-LASIK or “Blade-Free LASIK”</span></h2>
<p>This is a method to correct refractive errors such as myopia, hyperopia, and astigmatism using a device called a femtosecond laser to create a thin corneal flap instead of using a microkeratome blade as in traditional LASIK. Then, an excimer laser is used to reshape the corneal curvature to correct myopia, hyperopia, or astigmatism.</p>

<h2><span style="color: #00826a;">SmartSight (ReLEx) Blade-Free Technology for Correcting Myopia and Astigmatism</span></h2>
<p>SmartSight is the most advanced treatment for refractive errors today, using a laser to reshape the corneal curvature by separating the corneal layers into a lenticule within the corneal tissue and then removing the excess corneal tissue through a small incision of 2-5 mm. It is developed from the traditional ReLEx surgery with AI systems controlling and calculating the shape of the lenticule and iris recognition technology to track eye movement and rotation before and during surgery, resulting in highly accurate and more effective correction, especially for astigmatism.</p>
