Early Clinical Outcome of Hyperopic Small Incision Lenticule Extraction (SMILE) Using the VisuMax 800 in South Korea:...

Area of Science:

• Ophthalmology
• Refractive Surgery
• Laser Vision Correction

Background:

• Small Incision Lenticule Extraction (SMILE) is a popular refractive surgery procedure.
• Hyperopic SMILE addresses farsightedness, a common refractive error.
• Advancements in femtosecond laser technology aim to improve SMILE outcomes.

Purpose of the Study:

• To evaluate the early clinical outcomes of hyperopic SMILE using the VisuMax 800 femtosecond laser.
• To assess the safety, efficacy, and refractive predictability of the procedure.
• To determine the centration accuracy of hyperopic SMILE with this new platform.

Main Methods:

• Retrospective analysis of 11 eyes from 7 patients who underwent hyperopic SMILE.
• Utilized the VisuMax 800 femtosecond laser for the procedure.
• Evaluated outcomes including visual acuity, refractive error, and corneal topography up to 3 months postoperatively.

Main Results:

• High refractive predictability: 72.7% within ±0.50 D and 100% within ±1.00 D of target.
• Good safety profile: No eyes lost two or more lines of corrected distance visual acuity (CDVA).
• Accurate centration: Median decentration of 0.064 mm, correlating with higher-order aberrations.

Conclusions:

• Hyperopic SMILE with the VisuMax 800 shows favorable early clinical outcomes.
• The procedure offers high centration accuracy and potentially shorter surgical times.
• Further prospective studies are needed to confirm long-term stability.
