Advanced personalized nomogram for myopic laser surgery: first 100 eyes

Area of Science:

• Ophthalmology
• Refractive Surgery
• Corneal Surgery

Background:

• Myopia remains a significant refractive error globally.
• Laser-assisted in situ keratomileusis (LASIK) and laser-assisted subepithelial keratectomy (LASEK) are common surgical treatments for myopia.
• Achieving precise refractive outcomes is crucial for patient satisfaction and visual function.

Purpose of the Study:

• To evaluate the efficacy and safety of a novel advanced nomogram for myopia correction.
• To assess treatment accuracy, predictability, and patient satisfaction following LASIK and LASEK using the new nomogram.

Main Methods:

• Prospective interventional case series of 58 patients (100 eyes) undergoing myopia correction.
• Treatments included LASIK and LASEK performed by a single surgeon using the Zyoptix 217 Z100 excimer laser with an advanced nomogram.
• Postoperative outcomes, including refraction, uncorrected visual acuity (UCVA), and patient satisfaction, were assessed at 3 months.

Main Results:

• Excellent refractive outcomes were achieved in both LASIK and LASEK groups, with mean spherical equivalent close to emmetropia.
• High rates of uncorrected visual acuity of 20/20 or better were observed (95% LASIK, 97% LASEK).
• Hyperopic overcorrection (> or = +1.00 D) occurred in only 4.1% of patients, and patient satisfaction was high.

Conclusions:

• The advanced nomogram significantly improved treatment accuracy for myopia correction.
• The new nomogram reduced hyperopic overcorrection and the need for enhancement procedures compared to previous studies.
• High patient satisfaction and excellent visual outcomes support the use of this advanced nomogram in refractive surgery.
