FAQ for LASIK (Laser-Assisted in Situ Keratomileusis)

1How long dose LASIK take?

It usually takes 20 mins for both eyes. However, we suggest you stay for 2-3 hours for pre-operative preparations and examinations.

2Is it painless during LASIK?

Anesthetic eye drops are placed into your eye to achieve the effect of numbness, so there is usually painless during the procedure.

3Will I have an early presbyopia if I get LASIK done?

Presbyopia happens when the crystalline lens in the eye hardens and loses elasticity at the age around 40-50. It is an unavoidable age-related condition and has nothing to do with vision correction.

4Who is not suitable for LASIK?

People who:

  • have Incomplete eyeball development or unstable eyesight
  • have thin Cornea, or severely nearsighted / farsighted
  • are suffered from dry eye
  • have history of glaucoma or retinal problems
  • have Infection on cornea, such as inflammation or previous trauma
  • have history of immune system disease, such as rheumatoid arthritis or lupus
  • are pregnant
  • are in the needs of long-term steroid intake
5Is it a better idea to receive LASIK treatment in a hospital?

LASIK is a minimally invasive technology, which does not require general anesthesia. Only anesthetic eye drops are placed into your eye and you don’t need to stay after surgery. Our clinic is equipped with international level aseptic operation rooms with surgical instruments and advanced examination machines. The whole process is safe and reliable.

6Any risks do LASIK cause?

Risks come with all surgeries and they are relatively low with vision correction surgeries. The common risks are under-correction or over-correction, night vision worsens, dry eyes, etc. Complications come after vision correction surgeries are not common. Under rare circumstances, complications like corneal infection or bacterial infection might be happened.

7If I blink during the process of LASIK, will it affect the outcome?

No, anesthetic eye drops are placed into your eye and instrument will be used to avoid the lids from blinking. You can go through the whole process under instructions given.

8Can I use computer or watch TV after LASIK immediately?

Basically yes. However, we suggest that it is better to sleep for 4-6 hours or take one day off after surgery. A supine position is highly recommended and please put on the eye shield we provided to protect your cornea.

9Can I air travel same day after LASIK?

Basically yes. Eyes undergone laser surgery will not be affected by air pressure; therefore, it is OK to get on the plane. However, we highly suggest a follow-up visit one day after surgery for safety purposes.

10Can I wash my hair same day after LASIK?

We DO NOT recommend hair-wash same day after surgery to avoid unhygienic water getting into your eyes. If unhygienic water does get into your eyes, please use eye drops we prescribed and contact us as early as possible.

11Any diet restriction before or after LASIK?

No, you can have your normal diet.

12Can I get LASIK done if I have squint?

Theoretically, there is no confliction between squint surgery and LASIK. However, we recommend patients under 18-year-old to get squint corrected. For squint patients over 18-year-old, please consult your ophthalmologist before any surgical plan. For patients with accommodative squint, it’s an option to get vision corrected first and then get squint corrected if you do not want to improve vision with glasses. For patients with other types of squint, since squint itself might have already largely influenced your life and getting vision correction surgery will not benefit your original squint situation, therefore we won’t recommend you to have vision correction.

13Can I still have other eye surgeries after LASIK if necessary?

Yes. LASIK only changes the curvature of your cornea and other parts of the eyes are not involved.

14What types of patients are required to have LASIK Xtra or Cross-linking surgery?
LASIK Xtra is a type of corneal cross-linking surgery. It is suitable for patients: whose cornea is too thin, who has severe myopia, hyperopia and astigmatism or who is suspected of being at risk of keratoconus. Your surgeon will evaluate your conditions and decide if you need xtra cross-linking surgery before vision correction or not. Usually, riboflavin eye drops will be placed into your eyes and your eyes will be exposed to UVA light to strengthen your cornea. Cross-linking surgery can be simultaneously completed with LASIK.
