Laser in situ keratomileusis (LASIK) is a safe and predictable surgical option for correcting low to moderate hyperopia. This study demonstrates favorable visual outcomes and refractive accuracy in patients undergoing LASIK for hyperopic correction.

Area of Science:

  • Ophthalmology
  • Refractive Surgery

Background:

  • Hyperopia, or farsightedness, can significantly impact visual acuity.
  • Laser in situ keratomileusis (LASIK) is a surgical procedure aimed at correcting refractive errors.

Purpose of the Study:

  • To evaluate the efficacy and safety of LASIK for treating hyperopia.
  • To assess visual outcomes and refractive predictability following LASIK in hyperopic patients.

Main Methods:

  • A nonrandomized study involving 679 eyes of 321 patients undergoing LASIK for hyperopia.
  • Patients were stratified into three groups based on preoperative spherical equivalent: low (<2.00 D), moderate (2.00-3.00 D), and high (>3.00 D).
  • Postoperative outcomes measured included uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), and refractive stability.

Main Results:

  • Six months post-LASIK, high percentages of patients achieved emmetropia within +/- 1.00 D (Group A: 100%, Group B: 95.3%, Group C: 71.4%).
  • Excellent uncorrected visual acuity (20/40 or better) was reported in 94.1% (Group A), 100% (Group B), and 87.8% (Group C).
  • The majority of patients maintained or improved their best spectacle-corrected visual acuity, with 100% in Groups A and C, and 97.6% in Group B experiencing no loss or gain of 0-1 line.

Conclusions:

  • LASIK demonstrates predictability and safety in the surgical correction of low and moderate hyperopia.
  • The procedure yields favorable visual acuity and refractive outcomes for these patient groups.
