Farsightedness defines as when a patient sees far away objects clearly, but objects near become blurry. Another name for farsightedness is hyperopia. Hyperopia becomes caused when the eyeball does not curve enough or develops shorter than normal. Sometimes the lens sits farther back in the eye than normal, and that causes the condition. Either way when light enters the eye the images do not converge on the retina in the optimal spot creating a distorted image when sent back from the brain.
Signs of Hyperopia
If a patient finds themselves squinting excessively the possibility of farsightedness exists. If the eyes strain easily during activities, then a chat with the eye doctor may become necessary. Getting frequent headaches becomes another sign that hyperopia has occurred. The most obvious sign is of course blurry vision. Correcting the vision involves changing how the light enters the eyes and bends to land on the retina.
Procedures to Correct Hyperopia
Many people choose to use prescription glasses to correct hyperopia. As anyone who has glasses knows keeping up with a pair and maintaining can become inconvenient. Contact lenses remain another option for correcting farsightedness. The daily maintenance of caring for contact lenses and the expense of the liquid solutions over time can become issues. Another option is PRK otherwise known as photorefractive keratectomy uses a laser to carve the cornea into a flatter shape. For mild hyperopia new corneal rings called Intacs can become inserted that change the shape of the cornea, but like any insertion the body can reject it. As techniques have improved LASIK laser eye surgery has become one of the best options for many patients with farsightedness.
A study in the Journal of Refractive Surgery in 2015 posted results of a three year follow up of hyperopic LASIK surgery. The purpose of the study became to evaluate the long term outcomes of the surgery in correcting farsightedness. The study checked 86 eyes of 44 patients. The tool used was a sixth generation Amaris excimer laser. The findings are as follows 76% of the eyes had a distance visual acuity of 20/20. Then 29% eyes did not improve significantly and had to undergo retreatment. The first year after surgery had significant regression. To make sense of all the facts and figures talk to the staff at Sugarland Eye and Laser Center in Houston. They can answer most any question.
To change the shape of the eye so that the light bends at the correct angle into the eye a thin flap becomes created on the cornea. Once created this same flap becomes lifted up and the laser moves to the central cornea tissue where a circular pattern is cut. Now the cornea becomes steeper. The laser cuts precisely the amount needed according to the measurements the doctor has determined upon examination. The procedure can be performed in one day and no hospital stay is required. The best outcomes occur when patient and doctor work in cooperation with one another to determine all the best options and protocol.
Little or no pain is reported by patients after surgery. Many people see well within a day. A few report a burning or itching sensation for a short time. Someone may need to drive you home. It is suggested that regular checkups occur since in some patient’s regression does occur. Many can have the procedure done again.
