Objective evaluation [visual acuity test, manifest refraction, wavefront aberrations, the total cut-off value of the total modulation transfer function (MTFcut-off), and Strehl ratio (SR)] and subjective evaluation of visual quality (quality-of-life questionnaire) were conducted before surgery and at days 1, 7, 30, and 90 after surgery.\nRESULTS: A total of 47 patients (94 eyes) with SMILE and 22 patients (22 eyes) with tPRK were enrolled. The uncorrected visual acuity (UCVA) was better in SMILE patients on day 7 after surgery (1.13\u00b10.13 vs 0.99\u00b10.17, t=4.85, P&lt;0.001) but was comparable at days 30 and 90. At day 90, the SMILE group had a lower spherical equivalent (SE) than the tPRK group (0.04\u00b10.31 vs 0.19\u00b10.43, t=2.08, P=0.042). Total higher order aberrations (HOAs) were induced in both surgical types, which were more evident in the tPRK group with 3-mm pupil diameter (0.16\u00b10.07 vs 0.11\u00b10.05, t=4.27, P&lt;0.001) and 5-mm pupil diameter (0.39\u00b10.17 vs 0.36\u00b10.11, t=2.33, P=0.022). The MTFcut-off and SR showed a trend of improvement in both SMILE and tPRK patients but were statistically better in the SMILE group with both pupil diameters. There was a significant improvement of contrast sensitivity (CS) over baseline levels at the spatial frequency of 18 cycles\/degree (c\/d) in the SMILE group (F=2.72, P=0.033) and at 3 c\/d (F=3.03, P=0.031), 12 c\/d (F=3.72, P=0.013), and 18 c\/d (F=4.62, P=0.004) in the tPRK group. The subjective quality of life questionnaire showed a steady improvement in the SMILE group (F=8.31, P&lt;0.001) but not the tPRK group.\nCONCLUSION: SMILE and tPRK are both safe and effective ways to correct low and moderate myopia. A generally better and quicker recovery of visual quality favors the application of SMILE in qualified patients.<\/jats:p>","DOI":"10.18240\/ijo.2023.04.15","type":"journal-article","created":{"date-parts":[[2023,4,3]],"date-time":"2023-04-03T07:08:43Z","timestamp":1680505723000},"page":"608-615","source":"Crossref","is-referenced-by-count":6,"title":["A 3-month comparison study of subjective and objective visual quality of small incision lenticule extraction and transepithelial photorefractive keratectomy in patients with low and moderate myopia"],"prefix":"10.18240","volume":"16","author":[{"name":"Department of Ophthalmology, West China Hospital, Sichuan University, Chengdu 610041, Sichuan Province, China","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li-Xiang","family":"Wang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Tang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Ophthalmology, West China Hospital, Sichuan University, Chengdu 610041, Sichuan Province, China","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ke","family":"Ma","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Ophthalmology, West China Hospital, Sichuan University, Chengdu 610041, Sichuan Province, China","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hong-Bo","family":"Yin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Ophthalmology, West China Hospital, Sichuan University, Chengdu 610041, Sichuan Province, China","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ying-Ping","family":"Deng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Ophthalmology, West China Hospital, Sichuan University, Chengdu 610041, Sichuan Province, China","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7543","container-title":["International Journal of Ophthalmology"],"original-title":[],"link":[{"URL":"http:\/\/ies.ijo.cn\/en_publish\/2023\/4\/20230415.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,4,3]],"date-time":"2023-04-03T07:09:01Z","timestamp":1680505741000},"score":1,"resource":{"primary":{"URL":"http:\/\/ies.ijo.cn\/gjyken\/ch\/reader\/view_abstract.aspx?file_no=20230415&flag=1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,4,18]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2023,4,18]]}},"URL":"https:\/\/doi.org\/10.18240\/ijo.2023.04.15","relation":{},"ISSN":["2222-3959","2227-4898"],"issn-type":[{"value":"2222-3959","type":"print"},{"value":"2227-4898","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,4,18]]}}}
