Effects of blepharoplasty on the ocular surface and refractive status

AIM: To examine the effects of blepharoplasty on the ocular surface and refractive state.METHODS:Retrospective study. A total of 70 patients(108 eyes)who underwent blepharoplasty in our ophthalmology department from January 2022 to June 2023 were selected, among which 40 cases(48 eyes)diagnosed with ptosis received levator muscle shortness, and 30(60 eyes)diagnosed with eyelid laxity/single eyelids received blepharoplasty. The ocular surface disease index(OSDI), tear meniscus height(TMH), Schirmer Ⅰ test(SⅠt), tear film break-up time(BUT), corneal fluorescein staining(FL), cylindrical(Cyl), surface regularity index(SRI), surface asymmetry index(SAI), keratometry(Km), and cylindrical(C).RESULTS:There were statistical differences in preoperative and postoperative OSDI, BUT, SⅠt, and FL of patients who received levator resection(all P<0.05), but no differences were found in TMH(P>0.05). At 1 mo postoperatively, OSDI, BUT, SⅠt, and FL were significantly different compared to preoperative values(all P<0.05). There were no significant differences in OSDI, BUT, SⅠt, FL, or TMH of patients received blepharoplasty before and after surgery(all P>0.05). No significant differences were found in Cyl, SRI, SAI, Km, or C in either group before and after surgery(all P>0.05).CONCLUSION:The levator resection has an early impact on the ocular surface of patients with ptosis, and corneal protection measures should be taken early. There was no significant impact on patients undergoing blepharoplasty; there was no significant effect on the refractive status of all patients.
