Professional Experience/Performance Details
Mustafa TASELI, MD; He gained fame by operations in the field of; Pediatric Ophthalmology, and Adult
Strabismus, Contact Lens, Retinal Diseases, Eye Blood Pressure (Glaucoma), Refractive Surgery (Excimer
Laser), Macular Diseases, and Surgery, Oculuplasty, and Reconstructive Surgery, Uveitis, Cataract, and
Diabetic Retinopathy.
- More than 3.000 Laser Cataract Surgery – FAKO (Phacoemulsification)
Phacoemulsification is a modern cataract surgery in which the eye's internal lens is emulsified with
an ultrasonic handpiece, and aspirated from the eye.
- More than 1.000 LASIK or Lasik (laser-assisted in situ keratomileusis), PRK, and Smile Laser
LASIK or Lasik (laser-assisted in situ keratomileusis), commonly referred to as laser eye surgery or laser vision
correction, is a type of refractive surgery for the correction of myopia, hyperopia, and astigmatism.
PRK (photorefractive keratectomy) is a type of refractive surgery to correct myopia (nearsightedness), hyperopia
(farsightedness), and astigmatism. Like LASIK and other types of laser eye surgery, PRK works by reshaping the
cornea using an excimer laser, allowing light entering the eye to be properly focused onto the retina for clear
vision.
SMILE is considered the most significant advance in laser eye surgery technology in over 10 years. It combines
the safety of traditional vision correction techniques with even greater comfort and potentially greater precision.
- More than 1.000 Refractive Lens Exchange (lens replacement surgery)
Refractive lens exchange typically is for people with presbyopia or extreme farsightedness, for whom LASIK,
PRK or phakic IOL surgery generally are not suitable. Lens replacement surgery also can
correct myopia (nearsightedness), but generally it is not recommended when LASIK, PRK or phakic IOLs are
available.
An intraocular lens (IOL) implant is an artificial replacement for the lens of your eye. It's part of the surgery to
fix cataracts.
Monofocal IOL: This is the most common. Unlike your natural lens, which can stretch or bend to help
your eye focus, this implant stays focused at one fixed distance. If yours focuses at a distance, you might be able
to see things far away but need glasses to read or see close up.
Multifocal implant: Like glasses with bifocal or progressive lenses, this lens has areas that help you see things at
different distances. It could take several months for your brain to adapt so your vision seems natural.
Accommodating IOL: This flexible option acts more like your natural lens and focuses at more than one
distance. It makes you less likely to need reading glasses.
- More than 200 Vitrectomy Surgery
Vitrectomy is a type of eye surgery used to treat problems of the eye’s retina and vitreous. In this surgery, an
ophthalmologist may:
remove blood or other substance keeping light from focusing properly on the retina
remove scar tissue that is wrinkling or tearing the retina and causing poor vision
help repair a retina that has detached (pulled away) from the eye wall
remove a foreign object stuck inside the eye from an injury
- More than 200 Strabismus surgery
Strabismus surgery (also: extraocular muscle surgery, eye muscle surgery, or eye alignment surgery) is surgery on
the extraocular muscles to correct strabismus, the misalignment of the eyes.
- More than 200 Glaucoma surgery
Glaucoma is a group of diseases affecting the optic nerve that results in vision loss and is frequently characterized
by raised intraocular pressure (IOP). There are many glaucoma surgeries, and variations or combinations of those
surgeries, that facilitate the escape of excess aqueous humor from the eye to lower intraocular pressure, and a few
that lower IOP by decreasing the production of aqueous.
- More than 200 Pterygium surgery
A pterygium is a pinkish, triangular tissue growth on the cornea of the eye. It typically starts on the cornea near
the nose. It may slowly grow but rarely grows so large that the pupil is covered. Often both eyes are involved.
