Is Laser Eye Surgery safe for you?
Perhaps you’ve worn glasses since you were 5 years old and you’re getting pretty sick of it. Maybe you’ve tried contact lenses but you can’t get them in. Then once they’re in, you can’t get them out. Or they just fall out at the most inconvenient of times. Whatever the situation, laser eye surgery looks like a very tempting solution right now. But eyes are precious things and we only have two of them so the big question on your mind is – is laser eye surgery safe?
Laser Eye Surgery
Laser eye surgery is a general term referring to what is also known as refractive surgery. A type of procedure designed to surgically correct the optics of an eye to allow clear vision. Without the need for optical aids such as glasses or contact lenses. Although many people use the term “laser eye surgery” to refer to refractive procedures, not all methods use a laser.
All surgical procedures carry a degree of risk of adverse effects and complications. Laser eye surgery is no different. Setting aside the anatomy-specific complications. Making an incision through the body’s natural barrier of skin, membrane, or any other external surface tissue, immediately opens the way for potential infection. In laser eye surgery, all refractive procedures involve an incision in the cornea, the transparent dome at the front of the eye.
Certain laser eye surgery techniques are more invasive than others. So, carry specific risks that other techniques may not carry. With the development of new techniques and new technology, laser eye surgery procedures on the whole are becoming increasingly safer.
Is Laser Eye Surgery Safe?
Since booming in popularity over 30 years ago, laser eye surgery has been studied for its safety and efficiency. Statistics vary from study to study, depending on the particular refractive technique involved. But success rates are typically quoted as around 98-99%. This makes laser eye surgery one of the safest elective procedures in Australia. Complications involving a loss of visual acuity of more than one line on the letter chart has been reported as no higher than around 0.4%. Over 90% of patients undergoing LASIK are reported as achieving perfect 20/20 vision. Also known as 6/6 vision in Australia.
Many people fear that a complication during surgery may cause them to become blind. Fortunately, total loss of vision from refractive surgery has never been recorded in Australia. Studies have also been conducted on the safety and efficiency of various other laser eye surgery procedures. Including SMILE, PRK, and ASLA (advanced surface laser ablation). Most have concluded that they are all as safe and effective as LASIK.
Making the right decisions
It is important to note that some risks can be mitigated or avoided altogether. Something you’ll be happy to hear if you’ve been wondering how safe is eye laser surgery. One of the ways to do this is to ensure that you are a suitable candidate for any laser eye surgery procedure. And to ensure you have the surgery performed at a reputable clinic. Though it may be tempting to have laser eye surgery done overseas where it may be cheaper, medical standards and regulations, surgeon experience and the standard of equipment may be significantly poorer. This has the potential to increase your chances of experiencing a less-than-optimal outcome.
An experienced refractive eye surgeon will perform a thorough examination before advising you on the most suitable technique. This will take into consideration several factors:
There are prescription limitations for each surgical technique. Some offer a wider treatable range than others whilst still maintaining safety standards. Treating a certain prescription with an unsuitable technique can lead to under-correction. Residual refractive error or may result in the cornea becoming thin and weakened.
Several laser eye surgery methods such as LASIK, PRK, and SMILE, involve removing and reshaping select areas of corneal tissue. To better correct the optics of the eye. LASIK surgery also requires the formation of a flap of corneal tissue which is temporarily lifted away. This further reduces the amount of tissue available for reshaping. After the procedure is complete, enough corneal tissue must be left intact to maintain the integrity of the eyeball.
Certain laser eye surgery techniques are more suitable for certain lifestyles and vocations. For example, due to the creation of a corneal flap, LASIK carries the risk of flap-related complications. Such as debris getting caught beneath the flap or the flap becoming dislodged through trauma. Patients who engage in physically rough tasks or are often in dusty environments, may be directed away from LASIK. Towards a less risky procedure for their particular lifestyle, such as PRK or SMILE.
Pre-existing eye conditions.
The presence of various other eye diseases can affect the safety and final results of any refractive surgery. Careful preoperative examination and appropriate counselling can help patients to avoid undergoing laser eye surgery procedures that may exacerbate conditions such as dry eye disease or keratoconus, a corneal thinning condition. SMILE tends to pose less of a concern for dry eye compared to LASIK. Since it is a minimally invasive technique. While LASIK has been known to induce corneal thinning in patients susceptible to this condition.
Reduce surgical complications
Some surgical complications are a result of plain bad luck. But decrease them by following all pre- and post-operative instructions. Such as maintaining eyelid hygiene and adhering to prescribed eye drop medications. These will help to reduce your risk of adverse effects such as an eye infection.
Still wondering if laser eye surgery is safe and effective? Rest assured that it has been performed millions of times across the world to the satisfaction of millions of eyes. Very few procedures, if any, can boast a 100% success rate. But laser eye surgery shows very high levels of patient satisfaction and very low rates of complications.
