FAQ | Focus Clinics


• Should I opt for Blade-Free laser eye surgery?

At FOCUS we ONLY use a femtosecond laser for LASIK flap creation (the Ziemer LDV). All leading laser eye surgeons worldwide only now use femtosecond lasers due to their safety, accuracy and speed. If you are thinking about laser eye surgery ask the clinic if they use a microkeratome (blade) to perform some of their treatments. This is an old and out of date way of performing laser eye surgery and should be avoided.

• How much should I pay for laser vision correction?

For our treatment fees please visit the costs and finance page.

The cost of vision correction varies among practices, based on technology, surgeon experience and what the clinic includes in the fee. We are not the least expensive providers because we never sacrifice safety to save you money.

We have invested heavily in advanced laser technology and our diagnostic technology provides an incredible level of detail on your eyes and vision. This investment is extremely important to surgical results and our patients tell us they can see the difference, literally! We encourage you to visit other laser clinics and compare. If the clinic you visit offers you laser eye surgery ‘from £395 an eye’ then ask if they use a Microkeratome to create the LASIK flap – this is a blade. Also check in wavefront optics are included in the price.

It’s only natural to want to get the best price, but remember quality and service are extremely important when it comes to medical care. Quantity and quality rarely come together. After all, your vision is one of your most important assets. The best way to find out exactly what your price will be is to come in for an exam. After a comprehensive evaluation to determine what procedures you’re a candidate for and what degree of correction you need, we will be able to give you a specific price.

• What is 20/20 vision?

Vision letter test chartsThe most common way to measure vision is using standard letter charts, with a single large letter at the top and rows of smaller letters down the chart below.

In the United Kingdom, the standard placement of the eye chart is on a wall that’s 20 feet away from your eyes. Since many eye doctors’ rooms aren’t 20 feet long, in a smaller room the eye chart may hang behind the patient chair, using mirrors to make it appear in front of you at a simulated distance of 20 feet.

So if you can read the letters on the ’20′ line (which is the green shaded line at the lower end of the chart) from 20 feet away – then congratulations, you have 20/20 eyesight.

According to the American Optometric Association, “20/20 vision is a term used to express normal visual acuity (the clarity or sharpness of vision) measured at a distance of 20 feet. If you have 20/20 vision, you can see clearly at 20 feet what should normally be seen at that distance. If you have 20/100 vision, it means that you must be as close as 20 feet to see what a person with normal vision can see at 100 feet.

The driving standard is 20/40 where the chart letters are twice as big as those on the ’20′ line. If you have to stand at 20 feet away to be able read this bigger letters, when your normal sight friend can still pick them out from 40ft away, then you have 20/40 vision (the red back coloured line on this chart)

“20/20 does not necessarily mean perfect vision. 20/20 vision only indicates the sharpness or clarity of vision at a distance. There are other important vision skills, including peripheral awareness or side vision, eye coordination, depth perception, focusing ability and color vision that contribute to your overall visual ability.”

It is possible to see even better than 20/20, which are usually the last 2 rows on the chart (lines are below the shaded green chart area line). These are called 20/16 and 20/12).

So 20/20 is really just a good vision benchmark similar to, say, 100 MPH on a speedometer being a measure of high speed. It is possible to travel faster or slower than 100 MPH, but 100 is usually fast enough for most people! Likewise, 20/20 is not a final speed, a terminal velocity, it’s a weigh-station along the way to even better vision.

And Focus is one clinic with an absolute target that all patients see 20/20 or better after Z-LASIK or PRK with us.

• Will I have 20/20 vision following laser vision correction?

Committed to 100% 20/20
The goal of any refractive surgical procedure is to reduce your dependence on corrective lenses. However we cannot, nor can any clinic, guarantee you will have 20/20 vision as a result, although that is the most common outcome our patients, confirmed from our own results audit. Our commitment to a 100% success rate for 20/20 and better has taken us to new levels of excellence in clinical outcomes. And while this does not guarantee your individual success, our results from the past 2 years will give you a high degree of confidence that you will attain very clear unaided vision. These results are now undergoing a rigorous independent clinic audit and preparation for publication in a peer-review journal.

Our commitment to you is that we will not perform laser vision correction on you or anyone we feel does not have an excellent possibility of achieving independence from glasses and contacts. Our team is risk-averse, meaning that we do not take chances ourselves or on your behalf.

The vast majority of our patients are extremely happy with their results and can do most activities without dependence on corrective lenses after laser vision correction. For short sight, the great majority of patients can see better than 20/20 following their laser vision correction.

• Is laser vision correction safe?

Laser eye procedures are actually some the safest surgical treatments around. There are always possible risks with any technique and we encourage you to discuss these with us. Please note that treatments are available for almost all complications that affect your vision. Serious complications with LASIK or PRK are actually rare. The chance of having a complication, including various minor ones, from LASIK has been documented in previous clinical studies to be less than one percent, and based on procedures which used less sophisticated technology than we have available today.  In fact, it has been recently proven that there is a higher risk of infection from just wearing contact lenses.

Many of the risks and complications associated with this procedure can be reduced or eliminated through careful patient selection and thorough pre-operative testing using the latest diagnostic technology. That is why FOCUS has invested so heavily in sophisticated technology.

After laser eye treatment, you may experience some visual side effects. These are usually mild and most often diminish over a few days to a few weeks. But there is a slight chance that some of these side effects won’t go away completely, such as feelings of dryness, glare and haloes. If after a thorough examination we decide you are a good candidate for laser vision correction, you will be given additional information about the procedure that will allow you to make an informed decision about whether to proceed. Be sure you have all your questions answered to your satisfaction.
