“…To note, the presence of CNV and being female contributed to greater changes in the axial length per year. The study by Saka et al, in which changes in the axial length were examined using the IOLMaster, similar to our study, reported that a longer axial length at the initial examination resulted to a greater changes in the axial length per year [7]. However, in our stepwise analysis, the axial length at the initial examination was not selected.…”

“…However, A-scan ultrasonography was used in their study. Later, Saka et al, used the IOLMaster, which allows more accurate and non-invasive measurements of the axial length, to examine 185 eyes of 185 high myopia patients (mean age at the initial examination, 48.4 ± 12.2 years) without a history of intraocular surgery and any active fundus diseases, and observed a significant increase in the axial length from 29.35 ± 1.80 mm to 29.48 ± 1.85 mm over a 2-year period [7]. The highly myopic eyes with no complications group in our study also showed an increase of mean axial length from 29.01 ± 1.6 mm to 29.11 ± 1.6 mm, supporting the results of Saka et al However, their reported changes in the axial length per year was 0.06 mm, which is greater than that found in our study of 0.04 mm per year.…”

“…However, in a recent longitudinal study by He et al, slight increase of the axial length in adults (mean refractive error, −0.44 ± 2.21 diopters) was reported [4]. Conversely, an increase in the axial length in adults with highly myopic eyes is common and has been previously shown in longitudinal studies [5–7]. However, to the best of our knowledge, there have been no studies directly comparing the increase in the axial length in adults with non-highly myopic eyes or highly myopic eyes.…”

“…However, to the best of our knowledge, there have been no studies directly comparing the increase in the axial length in adults with non-highly myopic eyes or highly myopic eyes. In addition, because previous studies on the axial length in highly myopic eyes have not compared between eyes with and without macular complications [5–7], their influence on the axial length remains unknown. Thus, we investigated how changes in the axial length differ between non-highly myopic and highly myopic eyes with or without complications, particularly CNV and MTM.…”

PurposeTo investigate changes of the axial length in normal eyes and highly myopic eyes and influence of myopic macular complications in Japanese adults.Study designRetrospective longitudinal case series.MethodsThe changes in the axial length of 316 eyes from 316 patients (mean age, 63.8 ± 9.0 years; range, 34–82; 240 females) examined using IOLMaster with a follow-up period of at least 1 year were studied. This study included 85 non-highly myopic eyes (|refractive error| ≤ 5 diopters; 63 females; non-highly myopic group), 165 highly myopic eyes (refractive error ≤ −6 diopters or axial length ≥ 26 mm; 124 females) without macular complications (no complications group), 32 eyes (25 females) with myopic traction maculopathy (MTM group), and 34 eyes (28 females) with myopic choroidal neovascularization (CNV group).ResultsAll groups showed a significant increase in the axial length during the follow-up period (mean follow-up, 28.7 ± 16.8 months; range, 12–78) (P < 0.01). Changes in the axial length/year in the no complications group (0.041 ± 0.05 mm) were significantly greater than those in the non-highly myopic group (0.007 ± 0.02 mm) (P < 0.0001). Furthermore, changes in the CNV group (0.081 ± 0.04 mm) were significantly greater than those in the no complications (P < 0.0001) and MTM (0.040 ± 0.05 mm) (P = 0.0059) groups, whereas no significant difference was found between the changes in the MTM and no complications groups (P = 0.91). Multiple regression analyses indicated that CNV eyes (P < 0.0001) and female patients’ eyes (P = 0.04) showed greater changes in the axial length/year.ConclusionsAll groups showed an increase in the axial length, which was greater for highly myopic eyes. In particular, CNV eyes showed greater increases, indicating that larger changes in the axial length may require careful follow-up.

To assess the long-term clinical outcomes of implantation of a lens consisting of a biocompatible collagen copolymer (Visian implantable Collamer lens [ICL]; STAAR Surgical, Nidau, Switzerland) for moderate to high myopia.Methods: We evaluated 56 eyes of 34 patients with myopic refractive errors of −4.00 to −15.25 diopters (D) who underwent ICL implantation and routine postoperative examinations. Before and 1, 3, and 6 months and 1, 2, and 4 years after surgery, we assessed the safety, efficacy, predictability, stability, and adverse events of the surgery.Results: Mean (SD) logMAR uncorrected and best spectacle-corrected visual acuities were −0.03 (0.23) and −0.21 (0.09), respectively, at 4 years after surgery. The mean (SD) safety and efficacy indexes were 1.19 (0.25) and 0.83 (0.29), respectively. At 4 years, 44 (79%) and 52 (93%) of the eyes were within ±0.5 and ±1.0 D, respectively, of the targeted correction. Mean (SD) manifest refraction changes of −0.24 (0.57) D occurred from 1 month to 4 years after surgery. No vision-threatening complications occurred during the observation period. Conclusion:Implantation of ICLs is safe and effective and provides predictable and stable refractive results in the treatment of moderate to high myopia during a 4-year observation period, suggesting its viability as a surgical option for the treatment of such eyes.
