Wavefront-optimized advanced surface ablation (ASA) shows better uncorrected visual acuity (UCVA) by 3 months compared to LASIK. ASA is an effective alternative for vision correction, with bilateral simultaneous ASA being a reasonable option.

Area of Science:

  • Ophthalmology
  • Refractive Surgery

Background:

  • Laser vision correction aims to improve visual acuity.
  • Wavefront-optimized LASIK and advanced surface ablation (ASA) are common refractive surgery techniques.

Purpose of the Study:

  • To compare early visual outcomes between wavefront-optimized advanced surface ablation (ASA) and wavefront-optimized LASIK.

Main Methods:

  • A retrospective comparative series of 136 eyes undergoing ASA and 136 eyes undergoing LASIK.
  • Data included preoperative characteristics, perioperative details, and postoperative visual acuity and refraction up to 3 months.
  • Topical mitomycin C was applied in all ASA cases.

Main Results:

  • LASIK provided faster initial visual recovery (1 day and 2 weeks).

Related Experiment Videos

  • By 3 months, ASA demonstrated superior uncorrected visual acuity (UCVA) and spherical equivalent (SE) refraction.
  • A higher percentage of ASA eyes achieved or surpassed preoperative best spectacle-corrected visual acuity (BSCVA).

    • Conclusions:

    • While LASIK offers quicker initial recovery, ASA results in better UCVA and SE refraction at 3 months.
    • Advanced surface ablation is a viable alternative to LASIK.
    • Bilateral simultaneous ASA is a practical option for patients based on early visual recovery data.
