“…All of these factors have a great influence on optical quality. A previous study has confirmed that pterygium results in a deterioration in the visual quality [ 24 ], and excision can lead to significant improvement that is consistent with our findings. Besides this, our study has demonstrated that the visual quality of the modified sutureless and glue-free group was superior to that of the suturing group both at 1 month and 3 months after surgery.…”

Background Modified sutureless and glue-free method is an effective and novel surgical approach for pterygium. We aim to evaluate optical quality in pterygium treated with the new method and investigate the clinical application of the Optical Quality Analysis System (OQAS) and Anterior segment optical coherence tomography (AS-OCT) to evaluate the pterygium surgery. Methods A total of 52 eyes of 52 patients with pterygium were randomly divided into 2 groups. After surgical excision, the bare sclera was placed with a tight fit limbal conjunctival autograft fixed via the modified sutureless and glue-free method in group 1 (26 eyes) and conventional sutures in group 2 (26 eyes). Objective scattering index (OSI), modulation transfer function (MTF) and Strehl ratio (SR) were measured using OQAS in both groups during the perioperative period. Pterygium diameter was measured on AS-OCT. Ocular surface disease index (OSDI) questionnaire also was used. Results The group 1 had significantly lower mean OSI, higher mean MTF, and higher mean SR at 1 month and 3 months after surgery (p < 0.05). The group 1 had significantly lower mean OSDI at 1 month (p < 0.05), while was similar to group 2 at 3 months (p > 0.05). Pterygium diameter positively correlated with OSI (r = 0.528, p < 0.001), while it negatively correlated with MTF (r = − 0.501, p < 0.001) and SR (r = − 0.174, p = 0.217) before operation. Conclusions The modified sutureless and glue-free method might be more advantageous in improving the optical quality during early postoperative recovery times and pterygium diameter affected optical quality. OQAS can be reliably used to evaluate postoperative outcomes.

“…In line with our hypotheses, after treatment, the levels of MTF cutoff and SR in the two groups increased, while the level of TF-OSI decreased, with higher MTF cutoff and SR and lower TF-OSI in the study group suggesting that the visual quality of the patients was improved and the tear film function was effectively restored. Some studies have also confirmed that Pterygium can impair visual quality, and pterygium excision can significantly improve visual acuity 6 months after surgery [ 18 ]. Also, in keeping with our hypotheses, the corneal horizontal curvature and corneal vertical curvature of the two groups were increased, and the CAD level was decreased.…”

Objective. To investigate the clinical study of acupoint massage combined with recombinant bovine basic fibroblast growth factor (rbFGF) ophthalmic gel combined with limbal stem cell transplantation on visual quality, corneal refraction, and aesthetic outcome in patients with pterygium. Methods. Sixty patients with pterygium treated in People’s Hospital of Lujiang County from March 2018 to May 2021 were randomized into the control group and the research group by the random number table method, with 30 cases in each group. The control group received rbFGF plus limbal stem cell transplantation. The research group was treated with acupoint massage additionally. Results. The total clinical effective rate in the study group was higher than that in the control group ( P < 0.05 ); after treatment, the modulation transfer function (MTF) cutoff and Strehl ratio (SR) levels in the study group were significantly higher than those in the control group, and the tear film-related objective scatter index (TF-OSI) was significantly lower than that in the control group ( P < 0.05 ); corneal horizontal curvature and corneal vertical curvature in the study group after treatment were significantly higher than those in the control group, and corneal astigmatism degree (CAD) levels were significantly lower than those in the control group ( P < 0.05 ); the levels of the break-up time (BUT) and Schirmer test (SIT) in the study group were significantly higher after treatment, compared with the control group ( P < 0.05 ); and the incidence of adverse manifestations in the study group was significantly lower than that in the control group ( P < 0.05 ). Conclusion. Acupoint massage combined with rbFGF ophthalmic gel combined with limbal stem cell transplantation is effective in clinical treatment of pterygium.

“…The OQAS can evaluate the full information on aberration, diffraction and scattering [8,28]. OQAS has been successfully used to evaluate ocular optical quality in various eye diseases such as cataracts [29], pseudophakic eyes [11], dry eyes [30,31], corneal surface disorders [32], even macular disorders [33], and exhibited good repeatability. However, still no study was reported using the OQAS to assess the optical quality in ptosis eyes.…”

Background: To evaluate the differences in the corneal higher order aberrations (HOAs) and optical quality of the ptosis eyes compared with the normal fellow eyes in the unilateral congenital ptosis patients. Methods: A matched case-control study was performed in 17 pairs of eyes in 17 unilateral congenital ptosis patients. The ptosis eye was enrolled in the ptosis group while the normal fellow eye was enrolled in the normal group. The HOAs obtained from Pentacam HR and the optical quality parameters obtained from optical quality assessment system (OQAS) were compared between the two groups. Results: There were significant difference in vertical coma and vertical trefoil on the anterior corneal surface between the ptosis group and the normal group (p＜0.05). The OQAS parameters in the ptosis group were significantly different from that in the normal group (p＜0.05). The vertical fissure height (VFH) showed significant correlation with the total HOAs, 3 rd HOAs and vertical coma on the anterior corneal surface (p＜0.05). Conclusions: Compared with the normal fellow eyes, the ptosis eyes showed significantly degraded optical quality. The eyelid position was important for the changes of corneal HOAs in the ptosis eyes. The reasons for the discrepancy of the OQAS parameters between the ptosis eyes and normal fellow eyes were multiple.
