Lens Replacement Surgery or LASER eye surgery is the operation performed for correcting the vision by eradicating the necessity of contact lenses and glasses. It is much identical to that of cataract surgery in which the cloudy lens is replaced with the clear ones.
Primarily, intraocular lens is used for correcting both near and distance vision. But it is mainly for the patients who are not eligible for LASIK eye surgery and want a permanent solution for both reading and distance vision. Read on to know more about this surgery from this blog.
How Lens Replacement Surgery performs?
The shape and size of the natural lens is tiny and gets suspended by the ligaments. It assists the natural lens to work effectively. During lens replacement surgery the natural lens is opened up to make plenty of space for artificial lens (mainly acrylic) to correct the vision. Although it is the basic of this surgery and it can be attained by a number of procedures.
The most conventional one is known as phacoemulsification. It is entertained by making a small incision of about 2 mm to obtain the accessibility to lens. Another new technique is there known as Femtosecond laser lens surgery. In this case, a Femtosecond laser is used for incision on cornea and 3D reconstruction for imaging the eye in proper way.
At last the lens breaks down to get removed from the eye. While planning to undergo refractive lens exchange numerous options are there waiting for you. You can perform clear lens extraction on either one eye or both eyes simultaneously. You have the right to learn about the type of intraocular lens used too.
For cataract surgery, you will get single vision lens for promoting the focal length either for near or distant vision. Interestingly, it act as real focus yet you have options to choose from such as multifocal lens (most usual one). The most effective laser eye surgery can give both distant and near vision at the same time.
Toric lenses are given to the patients dealing with astigmatism. Hence, the astigmatism patients should correct the problem at first by using any required lens and then prepare to undergo the surgery.
How recovery takes place post Lens Replacement Surgery?
The recovery of the surgery is entirely depended on whether it is done on both eyes and a single one. For single eye it can be problematic for correcting the distant vision. It can be only dealt by wearing the contact lenses on the non-operated eye. It happens as the other eye possesses the same power as it has before operation.
On getting both of the eyes operated blurred vision is common on the very first day. Over time, it will be relatively easier than ever. Within a week you can find more improved vision. However, it is highly recommended to avoid driving until you get recovered completely from the surgery.
But redness, slight discomfort and watering will persist for some time. If you experience any pain doctor consultation is needed on an immediate basis.
Is glasses needed post Lens Replacement Surgery?
This procedure is done on the basis of the measurement of intraocular lens required for you. Eye healing rate is another important aspect to look upon and hence glass-free can’t be conclusive. All you can expect an improved vision and realistically only 85-90% free from glasses. It means that glasses are only needed during driving cars otherwise you can perform your daily activity without it completely.
Even you may need the help of the glasses for minute tasks like needle threading and small prints. Although it is done to correct your vision yet it may fail to reach the level of contact lens and glasses. Moreover, these work slightly different from that of the surgery at the same time.
But it is sure that it is meticulously designed to proffer you the freedom from contact lenses and glasses but isn’t an ideal solution itself to correct the vision completely.
