Assessing oxygen saturation in retinal vessels in high myopia patients pre- and post-implantable collamer lens implantation surgery.

摘要: Purpose To determine whether posterior chamber phakic implantable collamer lens (ICL) surgery in high myopia patients impedes oxygen saturation of retinal vessels. Methods Mean and diameter blood vessels were measured before after ICL implantation to correct refractive errors (i.e. −6.00 −20.25 dioptres [D]), using an Oxymap T1 oximeter. Results In 17 eyes patients, the oximeter detected a small but significant decrease venules, 1-week postoperatively (compared preoperative measurements). Moreover, at 1 week implantation, patient had consistently contracted, compared measurements. By 1 month surgery, however, both vessel returned levels. Otherwise, no statistically difference arterioles was found when comparing their measurements implantation. Conclusion Stable levels vessels, as by oximeter, show would not leave lasting impact or adverse effects retina patients.
