Lasik Laser Eye Surgery by Eye Specialist
Smile Laser Eye Surgery is a type of refractive eye surgery that uses a laser to reshape the cornea, improving vision and reducing the need for glasses or contact lenses. It stands for Small Incision Lenticule Extraction and is a minimally invasive procedure.

Precision of the SMILE Procedure
With a total refractive strength of two thirds of the eye, the human cornea serves as a refractive surface. The light rays enter the eye through the cornea, are refracted, travel through the lens and internal eye structures, and finally arrive at the retina where they are focused to create a picture. You can alter the cornea's (and the eye's) refractive power by altering the cornea's curvature or form. The middle layer of the cornea, known as the stroma, is reshaped to accomplish this. The SMILE laser removes a microscopic layer of the stromal tissue it produces, known as the lenticule, which the skilled surgeon subsequently removes by a brief incision of 2 to 3 millimeters. This method is extremely accurate because the tissue removal has the effect of changing the corneal curvature to match the spectacle number (dioptric power) of the patient's glasses. The laser quickly and painlessly completes all of these tasks. The lenticule, a microscopic layer of the stromal tissue the SMILE laser creates, is removed by the laser and is then surgically removed by a qualified surgeon through a small incision of 2 to 3 mm. Because the tissue removal alters the corneal curvature to match the spectacle number (dioptric power) of the patient's glasses, this approach is incredibly exact. These tasks are all rapidly and painlessly accomplished by the laser.
Benefits of SMILE
1. Minimally invasive: SMILE involves creating a small incision and removing a lenticule from within the cornea, making it a less invasive procedure compared to other laser eye surgeries.
2.Single-step procedure: SMILE is a single-step procedure that requires only a laser and avoids the need for creating a corneal flap, as in LASIK. This reduces the risk of flap-related complications.
3.Faster recovery: SMILE typically offers a quicker recovery time compared to other laser eye surgeries. Patients often experience minimal discomfort and achieve good vision within a few days to a week.
4.Reduced dry eye symptoms: SMILE has shown to cause fewer dry eye symptoms compared to LASIK. This is because SMILE minimizes corneal nerve disruption and preserves more corneal biomechanical stability.
5.Preserves corneal strength: SMILE removes less corneal tissue compared to LASIK, making it a suitable option for patients with thinner corneas or those at a higher risk of corneal ectasia.
6.Enhanced safety: The single-step process of SMILE eliminates some potential complications associated with the creation of a corneal flap, such as flap dislocation or flap-related infections.
7.Predictable and stable outcomes: SMILE has been shown to provide predictable and stable long-term outcomes in terms of visual acuity and refractive correction.
