“…[3][4][5][6][7] Implantable collamer lens (ICL) implantation is now applied by more and more refractive surgeons to correct myopia, especially high myopia. 8 Thus, it now calls for reliable and convenient techniques pre-surgery to screen and record potential retinal lesions.…”

Importance: Identifying peripheral retinal lesions in high myopia patients before implantable collamer lens (ICL) surgery by nonmydriatic Optomap ultrawide field imaging. Background: To investigate specificity and sensitivity of nonmydriatic Optomap ultrawide field imaging for detecting peripheral retinal lesions in high myopia patients before ICL surgery. Design: Hospital-based, cross-sectional study. Participants: A total of 1725 high myopic eyes of 897 ICL surgery candidates were included in this study. Methods: Patients with high myopia were scheduled for routine ophthalmic examination before ICL implantation. Nonmydriatic Optomap ultrawide field imaging was applied for detecting potential peripheral retinal lesions before ICL surgery. Main Outcome Measures: Presence of peripheral retinal lesions. Results: Of 1725 eyes, 344 (19.94%) had peripheral retinal lesions in total; 75 (4.35%) eyes had holes/tears; 313 (18.14%) eyes had peripheral retinal degenerations. Sensitivity of Optomap for detecting peripheral retinal holes/tears and degenerations were 57.33% (95% confidence interval [CI]: 45.38-68.69) and 65.18% (95% CI: 59.61-70.45). Specificity for peripheral retinal holes/tears and degenerations were 99.58% (95% CI: 99.13-99.83) and 99.08% (95% CI: 98.43-99.51), respectively. A total of 22.70% (32/141) of omitted peripheral retinal lesions under Optomap needed intervention. Longer axial length (odds ratio [OR]: 1.16, P < .01), more severe refractive error (OR: 1.05, P < .01) and older age (OR: 1.03, P < .01) were proved to be risk factors for peripheral retinal degenerations in high myopes. Conclusions and Relevance: Optomap ultrawide field imaging is a reliable adjunctive tool with high specificity and moderate sensitivity for identifying and recording peripheral retinal lesions in high myopes in preoperative Danjuan Yang and Meiyan Li contributed equally as first authors.

“…Under the same indoor light, all measurements were performed by the same ophthalmologist three times, and the average values were recorded. For the vault at 1 month after surgery, 250-750 µm was de ned as normal vaulting, < 250 µm as low vaulting, and > 750 µm as high vaulting [27,28]. At the same time, visual acuity, IOP, and diopter were measured.…”

Background: The prediction of implantable Collamer lens (ICL) vaulting is one of the most important parameters for ICL implantation for safety, aqueous humor circulation, and lens transparency.Methods: This was a retrospective study. A RESCAN 700 was used for intraoperative observation of vaulting. Spectral-domain optical coherence tomography was used for imaging. Results: Finally, 51 patients (102 eyes) were included in the study. Compared with the eyes with normal vaulting, those with high vaulting had higher preoperative diopter values (P=0.039), lower preoperative corrected visual acuity (P=0.006), lower preoperative intraocular pressure (P=0.029), higher preoperative anterior chamber depth (P=0.004), lower preoperative crystalline lens rise (P=0.046), higher ICL spherical equivalent (P=0.030), higher intraoperative vaulting (P<0.001), and lower intraocular pressure at 1 month (P=0.045). The multivariable analysis showed that the only factors independently associated with high vaulting at 1 month after surgery was the intraoperative vaulting value (odds ratio=1.005, 95% confidence interval: 1.002-1.007, P<0.001). The intraoperative and 1-month postoperative vaulting values were correlated (R2=0.562).Conclusions: The RESCAN700 system can be used to perform intraoperative optical coherence tomography to predict the vaulting value at 1 month.

“…The implantable collamer lens (ICL; STAAR Surgical, Monrovia, CA), a posterior chamber phakic IOL (pIOL), has a history of 30 years in refractive surgery around the world. 22 The procedure can be used to correct a higher range of ametropia than LVC. Some patients may be better candidates for ICL implantation due to pupil size, dry eyes, inadequate tissue volume for LASIK, abnormal topographic shape or personal preferences for a reversible procedure.…”

Purpose: To compare the prevalence of dry eye disease (DED) as determined by signs and symptoms in patients with a history of laser vision correction (LVC) or implantable collamer lens (ICL) implantation 5-15 years ago with a matched control group with no history of refractive surgery. Patient and Methods: This was a cross-sectional case-control study. The subject population included patients who had LVC or ICL 5 to 15 years ago. The control group was age matched. A test eye was randomly chosen. Subjects were required to have good ocular health. DED was evaluated using categorical cut-off criteria for tear film osmolarity (measured in both eyes), the subjective Ocular Surface Disease Index (OSDI), the dynamic Objective Scatter Index (OSI), non-invasive keratography tear break-up time (NIKBUT), meibography, and the Schirmer 1 test. Results: The study included 257 subjects (94 LVC, 80 ICL, 83 control). The frequency of hyperosmolarity was significantly higher in the LVC group vs the control (73% vs 50%, p = 0.002), In contrast, the frequency of subjective symptoms tended to be lower in the LVC group than in the control group (19% vs 31%; p = 0.06). These differences were not seen between the ICL and control group. Conclusion: The results suggest that LVC may cause tear film instability as indicated by hyperosmolar tears up to 15 years after surgery, with few subjective symptoms of dry eye. This may have implications for IOL calculations for cataract or refractive lens exchange later in life.
