Question 1

Is YAG laser the same as cataract surgery?

Accepted Answer

No. Cataract surgery is a separate, earlier procedure that removes the cloudy natural lens and replaces it with a clear artificial intraocular lens (IOL). YAG laser capsulotomy is a 5-minute outpatient laser procedure performed months or years later, specifically to treat the cloudiness that can develop on the lens capsule behind the IOL. If your vision has become cloudy again after successful cataract surgery, YAG laser — not repeat cataract surgery — is the solution.

Question 2

Is the YAG laser procedure painful?

Accepted Answer

No. Only topical anaesthetic eye drops are used. There are no injections, no incisions, and no physical contact with the eye. During the laser itself, patients typically see brief flashes of light and feel nothing. Mild irritation may occur once the anaesthetic drops wear off, which is managed with the prescribed anti-inflammatory drops.

Question 3

How soon will my vision clear after YAG laser capsulotomy?

Accepted Answer

Most patients notice significantly clearer vision within a few hours of the procedure as the debris from the disrupted capsule settles. Full visual improvement, including sharper visual acuity, reduced glare, and better contrast sensitivity, is typically achieved within 24 to 48 hours. Dr Khng will confirm your visual recovery at the one-month follow-up appointment.

Question 4

Can PCO come back after YAG laser treatment?

Accepted Answer

No. The YAG laser creates a permanent opening in the posterior capsule. Once the optical pathway is cleared, posterior capsule opacification cannot recur in the same location. This is a one-time, permanent treatment. You will not need a repeat capsulotomy for the same eye.

Question 5

What is the recovery time for a YAG laser capsulotomy?

Accepted Answer

There is no recovery period in the traditional sense. Most patients return to normal daily activities on the same day, with vision continuing to improve over the following 24 to 48 hours as debris from the treated capsule settles.

Question 6

Can I drive home after the YAG laser procedure?

Accepted Answer

We recommend arranging transport for the day of the procedure. The mydriatic drops used to prepare the eye will temporarily blur your vision and make you sensitive to bright light for several hours. Once the drops wear off, usually later the same evening, your vision and light sensitivity return to normal.

Question 7

What are the risks and side effects of YAG laser capsulotomy?

Accepted Answer

YAG laser capsulotomy is a very safe, well-established outpatient procedure with a low complication rate. Possible side effects include a temporary rise in intraocular pressure immediately after (monitored in clinic and managed with pressure-lowering drops if needed); new floaters in the days following treatment as capsule debris settles; and in rare cases, a small risk of retinal tear or retinal detachment. Dr Khng will discuss your individual risk assessment at the consultation, and the one-month follow-up includes a retinal check.

Question 8

What is the success rate of YAG laser capsulotomy?

Accepted Answer

YAG laser capsulotomy has a success rate of over 95%, making it one of the most reliably effective procedures in ophthalmology. The vast majority of patients notice a significant improvement in visual clarity within 24 to 48 hours, and the result is permanent.

Question 9

Can YAG laser capsulotomy go wrong?

Accepted Answer

Serious complications are rare. In a small number of cases, a temporary spike in intraocular pressure occurs immediately after the laser and is managed with drops in the clinic. A very small risk of retinal tear exists, which is why Dr Khng includes a retinal check at the one-month follow-up appointment.

Question 10

Is YAG laser capsulotomy covered by MediSave?

Accepted Answer

Yes. YAG laser capsulotomy is MediSave-claimable under TOSP code SL815L (Table 1C). Claims can be made from your own CPF MediSave account, or a spouse's or child's account. Most Integrated Shield Plans from AIA, Prudential, NTUC Income, and Great Eastern cover the balance above MediSave. Current claimable amounts should be verified at cpf.gov.sg. EyeWise Vision's team will assist with the pre-authorisation process.

Question 11

Is YAG laser capsulotomy safe and worth doing?

Accepted Answer

Yes. YAG laser capsulotomy is a well-established, non-invasive outpatient procedure with a very low complication rate and no incisions. For any patient experiencing hazy or glare-affected vision after cataract surgery, it is the definitive treatment and the only way to permanently restore the clarity achieved after the original operation.

Question 12

How many times can a YAG laser capsulotomy be done?

Accepted Answer

YAG laser capsulotomy only needs to be done once per eye because it creates a permanent opening in the posterior capsule that cannot cloud over again. There is no such thing as a repeat YAG procedure for the same eye once the capsule has been successfully treated.

Question 13

What percentage of people need a YAG after cataract surgery?

Accepted Answer

Up to 20% of patients who have had cataract surgery will develop posterior capsule opacification within two to five years of their operation. It is the most common complication of cataract surgery and is entirely treatable with a single YAG laser session at EyeWise Vision.

Question 14

Do you need new glasses after a YAG laser capsulotomy?

Accepted Answer

Most patients do not need a new glasses prescription because the procedure clears the clouded capsule without altering the focusing power of the eye. If your prescription has gradually shifted as PCO developed, Dr Khng will assess this at your one-month follow-up and advise whether an updated refraction is beneficial.
