PRK vs LASIK
PRK vs LASIK
It's hard to point out that PRK is healthier than Lasik or visa versa, however proponents of a technique to hone your skills on it and change into advocates of it. I personally choose PRK Lasik for the following reasons:
1. Preserves tissue / much less risk of ectasia
2. Eliminates the risk of stretch marks / skinny flap microstriae irregularities
3. Cortes much less nervous / much less dry eye
4. No threat of epithelial development
5. Eliminates the risk of dislocation of the flap down the road
6. No danger of DLK or accumulation of fluid in the interface
7. Studies on cadaver eyes that had LASIK liquid, whereas present alive within the interface on which all eyes. One concern is accumulation of fluid later in life, if the cataract surgery, retinal surgical procedure and glaucoma surgical procedure is necessary (or if inflammation, uveitis, other illnesses affecting the eye) because the space is there and fluid tends to accumulate in potential areas the place swelling or edema.
8. Threat of problems during flap surgery removed
9. Less horrifying to the patient throughout surgical procedure (without suction ring without mechanical units, etc.)
10. Simpler to improve (PRK just do it again) ... some of us hate relifting flaps due to increased danger epithelial growth.
11. Quality of vision in my experience in the long term is better with PRK.
The drawback of PRK is additional time to heal and get the most effective viewing quality. Some people also really feel there may be a slightly increased price of infection through the healing period, however for those who watch the sufferers very intently throughout this time, it is my perception that this danger may be very low. My practice affords Lasik and PRK to slam dunk candidate Lasik, PRK, but tends to push in PRK patients and affords solely all others who might have a barely elevated danger with LASIK than PRK (corneas, steep / flat, dry eyes , etc. K)
Now Epilasik with a microkeratome vs PRK is another argument, however I personally want PRK as a result of it's easier, cheaper, simpler, does not depend on costly gear proper job, less concern of the patient (the suction rings are afraid that they've positioned within the eye), there isn't any risk of stromal invasion of the leaf, and there is a danger that the suction ring itself and having hypertension within the eye while avoiding applies. Less complicated than I have seen no research or medical evidence to recommend that removing of the epithelium with a microkeratome / blade is best than doing it manually as we do within the PRK, so I'll take what I believe, safer and simpler although little question others disagree and have glorious arguments as to why you need a $ 50,000 machine to do what they will do without.
As for lasers considerations .... which is a totally different ball of wax. It is like comparing Porsches Vettes with arguments on both sides. The guy who drives the Vette like the Corvette and the guy driving the Porsche and the Porsche like when magazines take a look at them there is never a clear winner. I take advantage of the Visx S4 and I like .... for vary Correction CustomVue I think works very well. I have no experience with the Allegretto, but heard it works quite effectively and may make large areas of laser treatment of flying spot, but requires the removal of additional tissue. In the event you have a look at studies performed CustomVue patients with bigger pupils do very effectively with Visx CV. I think you possibly can examine this until your blue within the face and what's going to happen is that you end up selecting the physician's personal opinion or prejudices that seem to have developed or formulated at the same time doing analysis .
LASIK vs. PRK: The Reality about PRK
PRK, also known as "PRK is the unique form of laser eye surgery. Unlike LASIK, PRK, the physician applies the laser vitality on to the floor of the cornea. Due to this fact PRK requires no cutting tissue of the cornea.
Patients could determine to keep away from PRK because it has a imaginative and prescient restoration a lot longer. This is because of the fact that in the PRK laser eye treatment is applied to the surface of the eye moderately than deep within the cornea as in LASIK.
Whereas sufferers who've undergone LASIK can often see very effectively the day after therapy, PRK sufferers have to attend a week or two earlier than your vision is restored.
PRK patients are prescribed ache medication for a couple of days after surgery. In PRK patients the ache is due to the truth that ache fibers are found in the floor of the cornea, that are immediately exposed to laser.
Some sufferers can't freely decide if they wish to LASIK or PRK. Folks with very skinny cornea or pre-current situations are additional suitable for PRK, for example. All the time make your decision together with your doctor.
Entails the elimination of the extent of the higher surface of the cornea called the epithelium. This exposes the inside cornea which the computer assisted laser will start Resculpt the curvature of the eye.
No needles or incisions are required.
Eye medicines and use clear contact lenses are placed in each eye to prevent infection. These lenses are eliminated inside 2-5 days after surgery. The floor (epithelial) layer to regenerate and begin the therapeutic process can take up to 3-4 months. During that point eye medications will probably be used to promote therapeutic and prevent infection.
PRK sufferers usually take drugs to relieve ache for about 1-2 days after the operation. This is due to the fact that a lot of the ache fibers in the cornea is located on the surface and PRK are affected during surgery and the therapeutic process.
With PRK there's a small threat of problems arising from irregular healing response and / or infection. These can usually be handled with medication.
