LASIK West Chester, Kennett Square, & Paoli, PA
What is LASIK surgery?
LASIK is an eye surgery at Vistarr Laser & Vision in West Chester, Kennett Square, Paoli, PA, that corrects nearsightedness, farsightedness, and astigmatism. These common focusing errors of the eye are all attributed to the shape of the cornea, and LASIK reshapes the cornea. In LASIK, after a protective flap of tissue is created in the outer layer of the cornea (either with a surgical blade or a laser), the laser is then used to precisely reshape the cornea under the flap. The reshaped cornea then heals and because the light is refracted more optimally onto the retina, the patient’s vision is vastly improved.
Why Choose Vistarr for Laser Eye Surgery?
Our skilled and experienced eye surgeons will use the latest WaveFront technology to analyze your eyes and determine if refractive surgery is right for you. If so, they’ll customize the procedure to the unique structure of your eyes and deliver the highest quality care.
With a variety of options to choose from, including bladeless LASIK, almost anyone can improve their vision. We offer the following vision correction services:
Lasik (Laser-assisted in situ keratomileusis). During this surgery to correct vision problems a surgeon cuts a thin flap in the cornea then folds the flap to the side. Using a laser, the doctor reshapes the cornea underneath the opening. The flap is then laid back in place and the cornea heals without the use of stitches.
Epi-K (Epi-keratome). During this procedure, the surgeon accesses corneal tissue not by cutting a flap but by separating just the thin upper layer of the cornea known as the epithelium from the underlying layers of the cornea. The patient’s vision is then corrected using a laser, and the epithelium is removed.
LASEK (Laser Epithelial keratomileusis). This procedure involves preserving the extremely thin epithelial layer of the cornea by lifting it from the eye’s surface before using laser energy to reshape the cornea. The epithelium is then replaced on the eye’s surface. It may be a good choice for patients whose corneas are too thin or steep for other procedures.

How is Corrective eye surgery performed?
What is the eye surgery procedure?
- Preparation — Eye drops are applied to numb the eyes. Some patients also are given some sedation medication to relax them. Your eyelids are then propped open with a lid speculum.
- Accessing the cornea — The eye is stabilized, creating a feeling of mild pressure. Your surgeon then creates a thin flap in the cornea, providing access to the cornea. The flap is folded back.
- Reshaping the cornea — Using a computer-controlled excimer laser, your surgeon directs pulses of light at the eye, precisely reshaping the cornea.
- Replacing the flap — Once your cornea has been reshaped, the final step is to replace the corneal flap. It heals on its own without any sutures.
What is recovery like after laser eye surgery?
After your brief surgery, we’ll examine your eyes. Then you can return home, but you can’t drive yourself. After your surgery, you may have some slight itching or burning in your eyes, and you’ll probably have some additional tear production. These are normal signs of the healing process.
In most patients, vision is normal within eight hours and then continues to improve over time. In some cases, it can take several months to reach the full extent of your vision improvement. But in other patients, results are within a few weeks with a dramatic improvement in just hours.
