Refractive errors are the most common eye complications that plague millions of people all over the globe. The three main refractive errors are hyperopia also known as farsightedness, myopia also known as nearsightedness, and astigmatism. The most common solution for people with refractive errors is to wear corrective lenses which may come in the form of glasses or contacts. The lenses help adjust the light so as to correct the focus of light onto the retina which has become unfocused due to the irregular shape of the cornea.
However, there are other solutions to help correct the vision of a person who suffers from refractive errors. Many patients will find these solutions in a Houston Eye Center which has all the available facilities and equipment as well as skilled and well-trained eye surgeons who can work these tools in order to correct vision. Today, we are going to take a look into five other solutions in correcting a person’s vision which comes in the form of refractive surgery.
1.) Conductive keratoplasty – Also known as CK treatment, conductive keratoplasty is a form of refractive surgery which is used by eye surgeons to provide temporary treatment to patients who are suffering from presbyopia and hyperopia. The process involves aiming radiofrequency waves at the peripheral area of the patient’s corneas causing them to shrink as well as making the central area of the cornea steeper. Regression occurs within a few years but CK shrink is quite safe.
2.) Lasik eye surgery – Lasik Surgery is the surgical procedure of reshaping a patient’s cornea in a process known as ablation so that the light is focused properly onto the retina. To reshape the patient’s cornea eye surgeons make use of an excimer laser which is aimed onto the corneal tissue altering its form. Lasik surgery provides a great long term solution to refractive errors.
3.) Phakic intraocular lenses – When other forms of refractive eye surgery like lasik eye surgery are no longer a viable option, this treatment is used by eye surgeons. Patients who suffer from extreme myopia or nearsightedness are the ones who undergo this treatment. In the treatment lenses are implanted onto the patient’s eyes and can treat nearsightedness up to -20 diopters.
4.) Intracorneal ring segments – Also known as intact for short, intracorneal ring segments are used in treating patients who suffer from light cases of nearsightedness as well patients who have keratoconus. The intact is a thin plastic implant which is applied to the peripheral cornea of the patient. Once applied it helps make the corneas flatter from the center going out. Intacts are only for myopia of -3 diopters.
5.) Advanced surface ablation – This treatment is similar to Lasik Surgery involving an excimer laser in order to reshape a person’s cornea. The difference is that advanced surface ablation doesn’t require the eye surgeon to create a corneal flap in order to get to the underneath corneal tissue which is why it is considered a more advanced form of the ablation processed using in lasik eye surgery.
