LASIK

LASIK or Lasik (laser-assisted in situ keratomileusis) is a type of refractive surgery for correcting myopia, hyperopia, and astigmatism. LASIK is performed by ophthalmologists using a laser.LASIK is similar to other surgical corrective procedures such as photorefractive keratectomy, PRK, (also called ASA, Advanced Surface Ablation) though it provides benefits such as faster patient recovery...

Squint

At birth a baby's vision is very immature, with an acuity of around 3/60. Visual experience in infancy and childhood has a major influence on the development of the visual pathways, particularly the visual cortex. During the critical periods of visual development visual acuity develops as do other modalities such as contrast sensitivity, colour, pattern and motion perception...

Fuchs’ corneal dystrophy

Fuchs’ dystrophy is a disease of the cornea and occurs when cells in the corneal layer also called endothelium die off. The cells pump fluid from the cornea to keep it clear. However, when the cells die fluids build up and the cornea get swollen and puffy and vision becomes cloudy and hazy.

Post Lasik Ectasia

Post Lasik Ectasia is similar to Keratoconus where the cornea starts to bulge outward after LASIK eye surgery. Post-LASIK ectasia is caused by removing too much corneal tissue during LASIK surgery leaving the remaining corneal tissue too thin thus weakening the cornea and allowing it to bulge under normal eye pressure.
