AIM: To evaluate the long-term clinical efficacy of Shotfile software for the myopia patients with presbyopia.

METHODS: A total of 43 cases(82 eyes)over the age of 35 myopia patients were treated with laser corneal surgery in our hospital, added Shotfile software at the same time, and followed up for 3a. The uncorrected visual acuity(the distance and near vision), diopter change and visual satisfaction rate were observed at 1, 2 and 3a after operation.

RESULTS: At 1a after operation, there were 81 eyes(99%)with the uncorrected distance visual acuity reached the preoperative best corrected visual acuity, and 75 eyes(91%)with the uncorrected near visual acuity above 0.66, the average value of the spherical equivalent was(-0.64±0.63)D, the overall satisfaction rate was 91%. At 2a after operation, there were 79 eyes(96%)with the uncorrected distance visual acuity reached the preoperative best corrected visual acuity, and 69 eyes(84%)with the uncorrected near visual acuity above 0.66, the average value of the spherical equivalent was(-0.62±0.59)D, the overall satisfaction rate was 86%. At 3a after operation, There were 77 eyes(94%)with the uncorrected distance visual acuity reached the preoperative best corrected visual acuity, and 62 eyes(76%)with the uncorrected near visual acuity above 0.66, the average value of the spherical equivalent was(-0.55±0.56)D, the overall satisfaction rate was 81%. Intraoperative or postoperative serious complications were not found in all the cases, 1 eye of spherical equivalent with -10.0D was found -1.75D back after 1a, respected the willingness of patient for the second correction.

CONCLUSION: Shotfile software for the patients myopia with presbyopia is safe and stable in the long-term clinical treatment, and the patient satisfaction is higher, but the near visual ability of some patients may be weakened with the prolongation of time, preoperative communication with patients should be fully.
