Detailed comparison of laser vision correction methods Astana Vision — Astana 2026

Today, modern ophthalmology offers several advanced methods of laser vision correction. Each of them has its own features, advantages, and limitations. At Astana Vision, special attention is given to SmartSight — the most modern and technologically advanced method available today. Let’s take a detailed look at how it differs from other popular technologies: SMILE, FemtoLASIK, and TransPRK.

Main differences between the methods

SmartSight is the most advanced approach (fully femtosecond), combining maximum precision with minimal intervention in the corneal structure. Unlike classic methods, it is completely flapless, which reduces risks and speeds up recovery.

SMILE also belongs to flapless femtosecond technologies. Its principle is also based on a femtosecond laser, forming a lens (lenticule) inside the cornea, which is then removed through a small opening. These methods are considered very safe and comfortable, but are inferior to SmartSight in terms of tracking and intelligent control.

FemtoLASIK is a well‑known and time‑tested method in which a thin corneal flap is first created using a femtosecond laser, and then correction is performed with an excimer laser. The presence of a flap increases the risk of certain complications compared to flapless technologies.

TransPRK is a completely surface‑based excimer method without flap creation. It is considered one of the gentlest on the deep layers of the cornea, but recovery after it is the longest and may be accompanied by noticeable discomfort in the first few days.

Key advantages of SmartSight

Eye tracking and control. SmartSight is equipped with the most advanced 6‑dimensional real‑time tracking and full intelligent cyclotorsion control (accounting for eye rotation when moving to a horizontal position). This ensures the highest correction accuracy, especially in astigmatism.

Depth of effect. SmartSight acts at a minimal corneal depth during lenticule formation, which is especially important for patients with relatively thin corneas.

Recovery speed. Most patients after SmartSight achieve good vision as early as the next day, without any restrictions. In comparison, after TransPRK, vision stabilizes in a minimum of 7–14 days.

Comfort and safety. The risk of dry eye with SmartSight is relatively minimal, and postoperative discomfort is practically absent. The method shows the highest accuracy in astigmatism compared to similar techniques. The risk of regression (return of myopia) is also minimal, thanks to the presence of a transition zone.

Astana Vision recommendations

SmartSight is the method of choice No. 1 for most patients due to its maximum accuracy, safety, and rapid recovery.

ReLEx SMILE is a good and reliable option as a modern lenticular surgery.

FemtoLASIK is used as the «gold standard» and has the broadest clinical indications and widest application.

TransPRK is used relatively rarely, mainly for certain anatomical features of the cornea.

If you are planning vision correction, the choice of method is always made individually after a thorough diagnostic examination. SmartSight currently offers the best combination of cutting‑edge technology, comfort, and predictable results.
