Refractive Surgical Problem

چکیده
A 32-year-old man planned to have laser in situ keratomileusis (LASIK) in both eyes. The preoperative manifest refraction was 6.50 + 1.00 80 in the right eye and 6.25 + 1.00 90 in the left eye, yielding a visual acuity of 20/20 in both eyes. Topography was normal. Ultrasound pachymetry was 581 mm in the right eye and 574 mm in the left eye. The LASIK procedure was performed with a femtosecond laser, creating an 8.8 mm, 110 mm flap without incident in the right eye. In the left eye, however, a dense opaque bubble layer (OBL) appeared to interfere with the laser dissection. When a flap lift was attempted, the flap adhered to the underlying stromal bed. Therefore, the LASIK was aborted in the left eye. Postoperatively, the uncorrected distance visual acuity (UDVA) was 20/20 in the right eye. There was no change in refraction or topography in the left eye. Figure 1 shows a slitlamp photograph of the left eye. Would you advise this patient to have the left eye treated and if so, when? What procedure(s) would you consider for the patient? If you elect to perform LASIK in the left eye, what would the flap parameters be; would you choose a microkeratome or femtosecond laser to create the flap?

The latest generation of intraocular lenses, the problem of the eye refraction after cataract surgery.
Nowadays cataract surgery is refractive surgery as well. Intraocular lens implantation is gold standard, but there is plenty types of intraocular lenses, monofocal, multifocal, accommodating, and toric. Problem is to pick up correct one according life style, profession, health status and age. The aim is review current possibilities in cataract, refractive surgery and aphakia management.
متن کامل[Intraocular lens power calculations in eyes with previous corneal refractive surgery].
Results of intraocular lens power calculation were lower than actual required power in eyes with previous corneal refractive surgery because the inaccurate readings of corneal power obtained from standard keratometry. This causes the unacceptable hyperopia after cataract surgery. With increasing of population undergone excimer laser refractive surgery, this problem will be an obvious problem in...
متن کاملLaser eye surgery for refractive errors.
Several laser and non-laser refractive surgical procedures have been used to modify the shape of the cornea and correct myopia, hyperopia, astigmatism, and presbyopia. Introduction of the excimer laser to reshape the cornea has resulted in remarkable developments in the correction of these refractive errors. Combined with other advanced ophthalmological instruments, laser refractive eye surgery...
متن کاملUsing the eigenvalues of the sound equation to determine the properties of materials
In this article, the eigenvalues of the sound equation are used to determine the refractive index. This refractive index helps to extract the acoustic components of the material such as the speed of sound in the material. This will help in identifying targets, especially in the field of signal processing. For this purpose, a method has been extracted that can be used to establish a relation bet...

متن کاملRecent advances in refractive surgery.
Refractive errors are some of the most common ophthalmic abnormalities world-wide and are associated with significant morbidity. Tremendous advances in treating refractive errors have occurred over the past 20 years. The arrival of the excimer laser has allowed a level of accuracy in modifying the cornea that was unattainable before. Although refractive surgery is generally safe and effective, ...
