Purpose
This study aims to evaluate the efficacy and safety associated with insufficient vault following the implantation of an intraocular lens (ICL-V4c) in patients diagnosed with low to moderate myopia.
Setting
Insufficient vault is a complication of Implantable Collamer Lens (ICL) implantation. Evaluating the efficacy and safety associated with insufficient vault following the implantation of an intraocular lens (ICL-V4c) in patients diagnosed with low to moderate myopia is necessary.
Methods
In this study, data were collected from 178 eyes of 97 patients who underwent ICL implantation.40 eyes from 28 patients were categorized into the insufficient vault group (vaults ranging from 50μm to 150μm),and the remaining 138 eyes from 69 patients comprised the ideal vault group (vaults ranging from 250μm to 750μm).The following examination parameters were compared between the two groups: visual acuity, computer-assisted optometry, non-contact intraocular pressure measurements,pentacam three-dimensional anterior segment analysis, itrace visual quality assessment, visual function questionnaires, and corneal endothelial cell count analyses.Follow-up assessments were conducted at intervals of one month, one year, and two years post-surgery.
Results
Two years post-surgery, there were no statistical differences between the insufficient vault group and the ideal vault group in the uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), spherical equivalent (SE), intraocular pressure (IOP), lens density (LD) and corneal endothelial cell count (CECC) (all P >0 .05).Two years post-surgery, the effectiveness indices for the insufficient vault group and ideal vault group were calculated as follows: 1.22±0.17 versus 1.17±0.18 with no statistically significant difference noted between them (t=-1.267 , P=0.209); The safety indices for both groups yielded results of 1.07±0.13 versus 1.05±0.10, also showing no statistical significance (t=-0.561, P=0.578).
Conclusions
Insufficient vault after ICL implantation in patients with low to moderate myopia does not impose any conspicuous negative repercussions on the patients. It manifests comparable subjective and objective visual attributes, thereby signifying that it represents a safe, efficacious, and satisfactory alternative.
