“…PreserFlo more strongly reduces IOP than XEN [ 10 , 11 ], although its outcomes remain inferior to those of TLE [ 12 , 13 ]. However, PreserFlo might cause fewer postoperative complications than TLE [ 13 ], require a less steep surgical learning curve [ 14 , 15 ], and bridge the gap between microinvasive glaucoma surgery and traditional filtering surgery [ 16 ]. There are limited data on detailed changes in visual acuity and ocular biometry following PreserFlo implantation [ 17 , 18 ], as data have only been reported for up to one week [ 18 ] and three months after surgery [ 17 ].…”

Background This study aimed to evaluate postoperative changes in ocular biometry following initial PreserFlo MicroShunt implantation and trabeculectomy. Methodology This prospective, observational study analyzed 27 cases of PreserFlo MicroShunt implantation and 29 cases of trabeculectomy performed by a single surgeon. Visual acuity, intraocular pressure, corneal curvature, central corneal thickness, anterior chamber depth, and axial length were assessed at baseline and postoperatively at one day, one week, two weeks, one month, two months, three months, and six months. Patients requiring additional surgery and those with missing data were excluded. Consecutive data were compared with the baseline values using multiple comparisons. Results In both groups, intraocular pressure was significantly decreased from baseline at all postoperative time points (all p < 0.01). Visual acuity decreased in both groups at one day and one week postoperatively. Corneal curvature remained unchanged in both groups throughout the six-month follow-up. Central corneal thickness increased at one day and one week postoperatively in the PreserFlo group, but not in the trabeculectomy group. Anterior chamber depth exhibited a significant decrease at one week postoperatively in both groups. Axial length significantly decreased postoperatively until three months in the PreserFlo group and at all postoperative time points in the trabeculectomy group. Conclusions Ocular biometry following PreserFlo and trabeculectomy had a similar tendency postoperatively.
