Eligible Candidates for LASIK Surgery in Singapore?
LASIK Surgery Criteria For Suitable Candidates in Singapore
LASIK surgery by and large takes less than a minute per eye operation. The treatment involves cornea reshaping wherein the surface portion of the eye that is protruding will be improved; so as to correct vision.
The first lasers that were used were broad beam lasers (about 6 mm) similar to a shower that splits into smaller beams from the main laser. The current laser technology that is being used is the “flying spot laser”. Before you think about undergoing LASIK, you have to know if you are included in the list of ‘eligible candidates’ for LASIK surgery.
Suitable candidates for LASIK surgery in Singapore will be those who are suffering primarily from any of the following eye conditions: nearsightedness, farsightedness and astigmatism. The operation is precise, and the laser specifically targets the cornea. The advantages of this laser eye treatment include a very smooth cornea shape, and increased accuracy and efficiency of the patient’s eye vision.
The defects of the eye can be determined by examination and applying the physics of refraction. You have to know more about this process so you can determine if you are included in the list of suitable patient for LASIK surgery that will be conducted in Singapore. Refraction happens frequently at the cornea, because of the substantial disparity between the directory of refraction in the cornea, as well as that of the air.
The eye will be adjusted in order to boost its focal length. This way, it will be able to focus on objects at different distances. A normal eye will be able to unite the light properly by altering the lens shape in order that both objects near and far will clearly be seen.
Nearsightedness occurs, when the cornea is overly shaped resulting in ‘more’ refraction. The light refracts, and the image that is formed in front of the retina will be somewhat altered.
To correct this dilemma for the patient suitable for LASIK surgery, the process starts with the eye surgeon temporarily shedding back the epithelium. The laser will be pointed towards the eye to remove small portions of the cornea. The cornea will be flattened in order to correct nearsightedness. The flattened corneas have a lower indicator of refraction than the previous ones.
Farsightedness is another dysfunction of the eye that occurs in many candidates for LASIK surgery. In farsightedness, the cornea is not arched enough. This condition causes the image focal point to be situated behind the retina. To correct this condition the eye surgeon will use a laser in removing the outer edge surrounding the cornea.
