Good vision depends on how well your cornea and lens focus light on the retina. (eyesurgeonspc.com)
By reshaping the cornea or implanting a lens inside the eye, light can be properly focused on the retina, leading to good vision without glasses. (eyesurgeonspc.com)
Additionally, luteolin fortifies the capillaries, prevents the capillaries fragility, which contributes to delivery of the nutrients, oxygen, and blood to the eye globe, thus preventing the visual impairment and degenerative changes of the crystalline lens, cornea, and retina, as well as normalizes the eye fundus pressure.

IOLMaster 700 from ZEISS provides this planning solution with biometry measurements and three imaging reports: an OCT scan to screen for pathology and anatomical anomalies, a reference image for intraoperative guidance with ZEISS CALLISTO eye, and a SWEPT-source OCT analysis of the posterior cornea for Total Keratometry (TK) corneal astigmatism measurements. (zeiss.com)
This difference in optical density between the air the corneal material combined with the fact that the cornea has the shape of a converging lens is what explains the ability of the cornea to do most of the refracting of incoming light rays. (physicsclassroom.com)

Healthy, unoperated corneas have a range of corneal SAs. (crstoday.com)
Most commonly, astigmatism is an inherited refractive (glasses prescription) vision disorder, but it can also be acquired following surgical complications (LASIK, SMILE, PRK, etc.) besides being the end result of a corneal infection (most likely from contact lenses), inflammation, dystrophy, or trauma. (gulanivision.com)
