Refractive vision problems happen when the shape of your eye keeps you from focusing as well as it could. The error may be due to the length of the eyeball (shorter or longer than normal), alterations in the shape of the cornea, or aging of the eye’s lens.
Common Refractive Errors
Four common refractive errors include the following:
- Nearsightedness or myopia. This refractive error represents the ability to see up close but problems with focusing in the distance.
- Farsightedness or hyperopia. This refractive error develops when patients cannot see things close to them but can see distant images.
- Older people develop this condition or the inability to see things up close because of the aging process.
- This vision error emerges when focusing becomes difficult because of the shape of the cornea.
The primary symptom noted from a refractive error is blurred vision. Other symptoms may include headache, eye strain, glare around bright lights, double vision, or haziness. People may opt for laser surgery to correct refractive errors or choose another innovative alternative such as an implantable contact lens in Singapore.
Also known as ICL, implantable collamer lenses or implantable lenses require outpatient surgery that lasts about 15 minutes. During the procedure, the surgeon inserts the lens in a small opening at the cornea’s edge. The lens is placed in front of the eye’s lens and behind the iris. One of the advantages of this type of surgery is that healing is fairly fast. Also, no stitches are needed for the procedure.
The best candidates for this type of surgery are people who experience exceptionally high refractive errors or those errors over 1000 degrees. By choosing ICL, certain visual symptoms such as starbursts or halos are less bothersome as they can be with LASIK or laser surgery.
When You Can Schedule Surgery
If you are a good candidate for ICL, customised lenses are made according to your prescription. The earliest surgery date typically falls one week after your initial eye exam. A branded lens known as Visian® has been approved by the Food and Drug Administration (FDA) in the US. Vision practitioners like this type of lens as it is both flexible and soft and therefore feels natural when worn.
When you have this type of lens implanted, you can experience a high quality of vision or eyesight that can be compared to high-definition images. Because the lens is made of natural collagen, the eye will not recognise the lens as a foreign object and therefore accepts it more readily.
If you compare ICL to LASIK, you will find a number of benefits that result in the following:
- Fewer problems with night vision phenomena such as starbursts or halos.
- No problems with dry eye, which is a common side effect of LASIK surgery
- A broad treatment range, thereby making a refractive procedure available to people who once could not undergo the surgery
- No need to remove the tissue of the cornea as in LASIK procedures
- No need to change the cornea’s shape
As you can see, contact implants of this kind can help you see better. Focus on the details today by going online and scheduling an appointment with a practitioner who offers this surgery choice.
