VISUAL CORRECTION AID
Types of Refractive Surgeries Available:
- LASIK (Laser-Assisted in Situ Keratomileusis)
- Surface ablation procedures such as Photorefractive Keratectomy (PRK), Laser Epithelial Keratomileusis (LASEK) or Epithelial Laser in Situ Keratomileusis)
- ReLEx® SMILE (Refractive Lenticule Extraction, Small Incision Lenticule Extraction)
- Implantable Collamer Lens (ICL)
Spectacles are a common method of vision correction. They are convenient, safe and affordable.
However, there are disadvantages of spectacle wear:
- Spectacles may be unsuitable in certain occupations (firemen and athletes) or in those with sporting lifestyles (scuba diving, martial arts)
- Spectacles may fog up in humid climates can be uncomfortable to wear or appear less attractive.
- Spectacles can be broken or lost.
Contact lens can be a good alternative to glasses. They are more aesthetically pleasing as they are ‘invisible’.
Different types of contact lenses are available (rigid or soft). The choice usually depends on the health of the eye and patient preference. In general, patients with eye conditions such as dry eyes and allergies tend to be less suitable for contact lens usage. In all cases, good hygiene and after care are crucial in order to minimise the risk of complications.
The side effects of contact lens use include:
- Corneal infections
- Corneal oedema (swelling) or the growth of new blood vessels (neovascularization) as a result of reduced oxygen delivery
- Corneal abrasions
- Allergic conjunctivitis (Giant papillary conjunctivitis)
- Ptosis (droopy eyelid)
Contact lens may not be a good choice if you:
- Are not able to maintain a meticulous hygiene routine
- Work for more than 8 hours at a stretch and find it inconvenient to remove them at work
- Have dry eyes or ocular surface problems
- Are prone to recurrent corneal infections
- Work in a dry or dusty environment
- Participate in water sports
Laser Vision Correction Surgery Can Improve The Quality of Life
All refractive eye surgical procedures aim to reduce the dependency on spectacles and contact lenses in order to improve the quality of life.
Studies have shown that quality of life is reduced in spectacle wearers, particularly those with higher corrections.
