Eyes are the great blessing of God. Through the eyes, we can ponder on the future vision. Healthy eyes are very important to enjoy life. To sustain the health of the eyes, doctors recommend food rich in vitamins, and fibre. The eye has many important sects that make the vision more clear. The cornea is the white part of the eye. It aimed to focus the light that has to enter the eye. With some abnormality in the gene, or invasion of disease, the cornea may flat and patients may face astigmatism. Astigmatism may make the cornea of the eye a football or egg-shaped similarly when we discuss about their causes of Astigmatism so it may cause eyeball flat or curved as well.
Flat Corneal Meridian:
The flat corneal meridian may cause blurredness in vision. The flat corneal meridian is a combination of short-sightedness or farsightedness. The common symptom of flat corneal meridian is headache, eye strain, problems in night vision, and squinting. The flat corneal meridian fault does not make the image on the retina.
Steep Corneal Meridian:
The steep corneal meridian is the treatment that the doctors prepare the eye for preoperative treatment. The steep corneal meridian purveys the significant torsional effect on the eye, it can maximize or minimize the corneal surface area for the investigation. The treatments mostly happen within three months. It evaluates the torque or flattening effect on the incision.
Incision Flattening TORIC:
After taking the cataract surgery, the incision flattening TORIC is studied to evaluate the functionality of the eye. The cornea of the eyes having the thickness of 714.5 µm and PCA greater than 0.35 D WTR astigmatism, purvey a significant number of incision flattening TORIC. It prepares the eye for -operative manifestation. Any abrupt change in the incision flattening TORIC affect the visual acuity.
Vector Planning For Hyperopic Astigmatism:
Topography-guided treatment is the basic step for vector planning for hyperopic astigmatism. The correct astigmatism is lain by the magnitude, and axis for the refractive cylinder the measurements are taken in the dioptre unit. The vector planning for hyperopicastigmatism depends on the two treatments. One is the manipulation of the correct use of the lens. The doctors mostly recommend the torsional lens. The second treatment involves refractive surgery. Mostly, the laser is used to replace the cornea of the eye.
Hyperopic astigmatism is an eye disorder in which the person sees distant objects, but the retina is not able to make the image of the nearby objects. The vector planning for hyperopic astigmatism involves the ASSORT software which is very advance software for Astigmatism treatment similarly this software can take the topography and tomography of the eyes.
