Our Experience Of Using Supracor Method In Refractive Surgery

This study aims to investigate the SUPRACOR method and evaluate the safety measures and effectiveness of the SUPRACOR excimer laser algorithm to treat presbyopia in hyperopes and myopes.

This is a retrospective case review of 25 patients (50 eyes) who have undergone SUPRACOR excimer laser treatment on both eyes.

The patients were subdivided into two groups: Group A (36 eyes, 18 patients) had hyperopia; and Group B (14 eyes, 7 patients) had myopia. The minimum follow-up period was 1 month. 

Preoperatively, for Group A -the mean manifest refraction spherical equivalent (MRSE) was +2.16±1.5D, the mean K-reading was 43.49±3.2D, astigmatism was up to 1.0D, mean uncorrected distance visual acuity (UDVA) and mean uncorrected near visual acuity (UNVA) was 20/60 (0.48LogMAR) and N12 (Jeager 8), respectively.

For Group B- the mean MRSE was -3.64 ±1.25D, the mean K-reading was 44.23±1.5D, astigmatism was up to 1.0D, mean UDVA and mean UNVA was 20/200 (1.0LogMAR) and N12(Jeager8) respectively.

 The recommended refractive target spherical equivalent (SE) was 0.0 for Group A, and -0.5D for Group B. The optical zone size was 6.0mm.

Patients’ manifest refraction, monocular and binocular distance, and near visual acuity measurements were obtained on the next day after surgery, 1 week and 1 month postsurgical follow-up. At 1 month postoperatively, the binocular mean UDVA and mean UNVA for both Group A and Group B was 20/25(0.1LogMAR) or better and N8(Jeager6) or better, respectively. The mean MRSE at 1 month postoperatively for Group A was +0.25D±0.1, with mean astigmatism -0.5D, for Group B was -0.25D±0.2, with mean astigmatism -0.5D.

SUPRACOR excimer laser algorithm is safe and effective for the treatment of presbyopia and provides similarly good binocular vision outcomes for hyperopes and myopes. However, further study of this method is necessary with the involvement of a larger group of patients and a longer postoperative follow-up period.
