In addition to general ophthalmology, Mr Dipak Parmar subspecialises in cornea, uveitis and cataract surgery. He performs modern corneal transplantation including penetrating keratoplasty and newer lamellar techniques such as big bubble anterior lamellar keratoplasty and posterior endokeratoplasty.
A small incision is made into the eye, the cataract is removed and replaced with an artificial lens. Artificial intraocular lenses, or IOLs, replace the eye's natural lens that is removed during cataract surgery. These days there are a number of different types of IOLs, all intended to serve a different medical need, such as IOLs for Astigmatism, Multifocal or Monovision and more. It is important for the patient to discuss his or her need in depth before choosing a lens. The procedure is performed under local anaesthetic as a day case.
A cataract is a condition affecting the lens of the eye. The lens is situated inside the eye behind the pupil and iris. Its normal function is to focus the light to ensure we see a clear image. A cataract is present when the lens, which is normally clear, becomes cloudy. This restricts the amount of light that is able to enter the eye, causing blurred vision, dazzle and glare. A lens implant is inserted into the eye to replace the cataract. In the majority of cases no stitches are required. The operation is normally carried out under local anaesthetic. Most patients have surgery as a day case, although some opt to stay in hospital over night.
Corneal transplantation, also known as corneal grafting, is a surgical procedure where a damaged or diseased cornea is replaced by donated corneal tissue (the graft) in its entirety (penetrating keratoplasty) or in part (lamellar keratoplasty). The graft has been removed from a recently deceased individual with no known diseases or other factors that may affect the viability of the donated tissue or the health of the recipient. The cornea is the transparent front part of the eye that covers the iris, pupil and anterior chamber. The surgical procedure is performed by ophthalmologists.
Your surgeon may recommend LASEK surgery if you have thinner corneas or are required to perform certain tasks in your day to day life. With Lasek surgery the outer protective layer of the cornea is gently repositioned after being softened by the surgeon. The laser then reshapes the eye in exactly the same fashion as LASIK surgery. The outer layer is then gently moved back into place and a contact lens is placed on the eye for up to seven days while the outer protective layer heals.
LASIK is an abbreviation for LASER Assisted In-situ Keratomileusis. It is the most commonly performed type of laser eye surgery to treat myopia (short sightedness), hyperopia (far sightedness) and astigmatism. A flap only approximately one tenth of a millimetre thick, is created on the cornea. The laser is then applied to the middle layer of the cornea (as opposed to the outer layer with Lasek syrgery). The laser takes only a few seconds to reshape the eye and correct your vision. The flap is then gently placed back onto the eye. The eye’s healing process is very efficient and will keep the flap firmly in place in just a few days following surgery.
LASIK, laser in-situ keratomileusis, issued to correct vision in people who are nearsighted, farsighted, or have astigmatism. The Wavefront method is a groundbreaking improvement over LASEK, designed to first map the cornea and produce a far more precise reshaping of the eye. This gives the treatment a far higher chance of achieving 20/20 vision and reduces the odds of vision impairing side effects.
