COVID-19 Update

We regret any inconvenience caused by the new protective measures, but our primary goal is the health and safety of everyone who enters our office.
The following procedures suggested by the Center for Disease Control & Prevention, American Academy of Ophthalmology, as well as Pennsylvania Medical Society are what we follow at Keystone Eye Associates.
1. All must wear a mask in order to enter the building.
2. Patient will remain in vehicles and enter the office only at your appointment time. If you arrive early, we will ask you to wait in your vehicle until your appointment time.
3. Patients and accompanying family members will be asked screening questions. Non-contact temperatures will be taken.
4. Person accompanying patient (1) will remain in vehicle unless patient requires assistance or is a minor. Multiple people may not enter the office.
5. Patients must reschedule if they are ill or exhibiting cold or flu like symptoms, have traveled to affected hot spots within the last 14 days or have been exposed to Covid-19. STAY HOME IF YOU ARE UNWELL.
6. We have reduced the number of patients per day to promote social distancing. You may be called to change your appointment to a different day or time.
7. Our staff use Personal Protective Equipment including masks, sanitizer, cough shields, and gloves if needed.
8. Frequent antiseptic wipe downs in the office and exam rooms between patients.
We love caring for our patients and look forward to seeing you. Please help us keep our patients, staff, doctors safe and understanding the strain we all feel during this time. Thank you!

Laser-Assisted In-Situ Keratomileusis (LASIK) is a safe, painless and reliable surgical eye procedure that corrects certain eye problems and reduces or eliminates the need for glasses or contact lenses. If you are weary of wearing contact lenses or eye glasses then LASIK may be the right option for you. LASIK consists of a laser eye surgery that treats certain eye problems and promotes clear and sharp vision. The ophthalmologists at Keystone Eye Associates in Philadelphia City are highly accomplished eye doctors who can correct eye problems with a LASIK treatment plan tailored to patients’ specific conditions and needs. What benefits can you achieve by LASIK from Keystone Eye Associates?

  • • Non-invasive procedure
  • • Safe and painless treatment
  • • No dependence on eye glasses or contact lenses
  • • Immediate & long-lasting results

What is LASIK and how is refractive surgery performed?
LASIK stands for Laser-Assisted In-Situ Keratomileusis, which is the most frequently, performed laser eye surgery to treat certain eye conditions which include nearsightedness (myopia), farsightedness (hyperopia) and astigmatism. LASIK is a type of refractive surgery in which the cornea (front part of the eye) is reshaped so that it bends (refracts) the light rays passing through the cornea with a more precisely focal point onto the retina (back part of the eye) thus, resulting in clear and sharp vision. The procedure of LASIK eye surgery usually takes 30 minutes or less and the patient is given anesthetic eye drops to numb the eye. During the procedure, the surgeon creates a thin protective flap in the cornea to access inner corneal tissue. Subsequently, the cornea flap is painlessly peeled back with the underlying corneal tissue being reshaped by using a laser. After the cornea is reshaped, the surgeon carefully repositions the cornea flap back into place allowing it to heal naturally within a few hours after the surgery without any need for stitches. The results of the refractive surgery depend on the specific refractive error and other factors. It often improves the vision without the need of eye glasses or contact lenses. Most patients are satisfied with the results since they are no longer dependent on their eye glasses or contact lenses for most of their daily activities.
What is Photorefractive Keratectomy (PRK) and how does it differ from LASIK?
Photorefractive Keratectomy (PRK) is a type of refractive surgery that uses laser energy to correct certain eye problems such as nearsightedness (myopia), farsightedness (hyperopia) and astigmatism. PRK is the first type of laser eye surgery that corrects the vision and it is predecessor to LASIK procedure. PRK is also a commonly performed procedure while offering more advantages over LASIK to some patients. Like other refractive surgeries, PRK also works by reshaping the cornea so that the light entering into the eye is properly focused on the retina for clear vision.The main difference between LASIK and PRK lies in the very first step of these procedures. In LASIK, a thin protective flap is created in the cornea, it is peeled back to expose underlying corneal tissue and then it is folded back after reshaping the cornea. But in PRK, the surgeon removes and discards the thinner top layer of the cornea (called as epithelium) and reshapes the underlying corneal tissue. Within a few days post-surgery, the epithelium layer repairs itself and grows backover the surface of the cornea.
What is Refractive Lens Exchange?
The procedure of refractive lens exchange is also known as clear lens extraction, in which the natural lens of the eye is replaced with an artificial lens, called an intraocular lens (IOL). Refractive lens exchange is the best option to treat high nearsightedness, high farsightedness and presbyopia without the cornea modification as done in LASIK. There are various types of IOLs available with the doctor selecting the suitable type of IOL that best treats each patient’s individual condition allowing for the best possible results. The procedure of refractive lens exchange is the same as that of cataract surgery procedure, but the only difference between both the procedures is that refractive lens exchange is performed to achieve the refractive correction, while cataract surgery is performed for cataract removal. The recovery time of refractive lens exchange is fast and patients see a dramatic improvement in their vision quality. The results appear immediately after the surgery with greater focusing power and clearer vision. The most important benefit of refractive lens exchange is that it eliminates the dependency on eye glasses or contact lenses. This procedure also prevents the patient from developing the cataracts in future.
