Characteristics of sulcus-to-sulcus diameter and intraocularcollamer lens sizing strategy in myopic patients with different diopters:a dual-meridian measurement based on ultrasound biomicroscopy
摘要
Abstract
Objective To investigate the distribution,differences,and correlations of horizontal and vertical sulcus-to-sulcus(hSTS/vSTS)diameters in myopic populations with different diopters,thereby providing a basis for the personal-ized sizing of intraocular collamer lenses(ICL).Methods A retrospective clinical study was conducted.Totally 122 my-opic patients(244 eyes)who underwent ICL implantation were enrolled,and according to spherical equivalent(SE),they were divided into the moderate myopia group(-6.00 D＜SE≤-3.00 D,45 eyes),high myopia group(-10.00 D＜SE≤-6.00 D,150 eyes),and ultra-high myopia group(SE≤-10.00 D,49 eyes).Ultrasound biomicroscopy was used to meas-ure hSTS and vSTS in all patients,followed by intergroup comparison and correlation analysis.Results The overall ciliary sulcus morphology was predominantly vertically elliptical(vSTS＞hSTS).Both hSTS and vSTS in eyes with ultra-high myo-pia were significantly larger than those in the moderate and high myopia groups(all P＜0.05),and the vSTS-hSTS differ-ence[(0.63±0.38)mm]was also significantly greater(all P＜0.05).The proportion of eyes with a vSTS-hSTS difference＞0.50 mm was highest in the ultra-high myopia group(57.14％).Correlation analysis revealed that SE exhibited an extremely weak or weak negative correlation with both hSTS and vSTS(r=-0.18,P=0.006;r=-0.24,P＜0.001),whereas hSTS was significantly positively correlated with vSTS(r=0.78,P＜0.001).Further analysis revealed that axial length(AL)and cor-neal curvature were key anatomical factors influencing STS(all P＜0.05).Multiple linear regression analysis showed that even after adjusting for all confounding factors,SE remained independently associated with the hSTS/vSTS ratio,which reflects the degree of vertical ellipticity(β=0.16,P=0.039).Conclusion Higher myopic diopters are associated with a more pronounced vertically elliptical morphology of the ciliary sulcus.In preoperative evaluation for ICL implantation,routine measurement of vSTS and hSTS is required,especially in patients with high and ultra-high myopia,to optimize ICL size selection and vault predictability.关键词
