A Nd:YAG laser photodisruption is a wellestablished tool for intraocular surgery, such as treatment of posterior capsule opacification that affects the visual function. During the intraocular procedure, called laser capsulotomy, the excitation pulse is focused several times just behind the posterior capsule and intraocular lens to create the central opening in the opacified capsule. We built an...
Intraocular lens development is driven by higher patient expectations for ideal visual outcomes. The recently US Food and Drug Administration-approved Softec HD(™) lens is an aspheric, hydrophilic acrylic intraocular lens (IOL). The hydrophilic design of the lens is optimized to address dysphotopsia while maintaining biocompatibility, optical clarity, resistance to damage, and resistance to bio...
Intraocular lenses (IOLs) are designed for implantation for vision correction following cataract removal. The IOL typically replaces a cataractous natural lens that exhibits very high levels of light scattering. The amount of scattering is significantly reduced with an IOL, though it is rarely quantified and both the surface and the bulk of the intraocular lens may contribute to light scatter a...
We report a patient with clinical ocular siderosis at the time of presentation but undetectable intraocular foreign body on computed tomography (CT) and ultrasonography. A 24-year-old man suffered from right ocular injury when hammering metal on metal. Slit-lamp examination revealed a small corneal perforating wound and an iris hole, but no intraocular foreign body was found under fundus examin...
PURPOSE To compare rates and severity of complications between infants undergoing cataract surgery with and without intraocular lens (IOL) implantation. DESIGN Prospective randomized clinical trial. METHODS A total of 114 infants were enrolled in the Infant Aphakia Treatment Study, a randomized, multi-center (12) clinical trial comparing the treatment of unilateral aphakia in patients under...
The leading topic of this particular paper is dedicated to available surgical options for refractive eye disorders treatment including surgery of cornea and intraocular surgery. Corneal Surgery includes laser refractive surgery - LASIK (Laser-Assisted In Situ Keratomileusis), FemtoLASIK (Femtosecond laser-assisted LASIK), PRK (Photorefractive keratectomy). This article describes relevant princi...
AIM To investigate the effect of the lens on outflow facility in Korean patients with cataracts. METHODS Intraocular pressure was measured by Goldmann applanation tonometry in 42 patients with cataracts and outflow facility was determined by tonography preoperatively, before and after instillation of pilocarpine. All patients received clear corneal phacoemulsification and silicone foldable in...
OBJECTIVE To determine whether texturing the optic edge of the intraocular lens reduces photic symptoms in patients with square-edged acrylic intraocular lense implants. METHODS Sixty patients underwent routine phacoemulsification performed by a single surgeon and were prospectively randomized to receive either the standard AcrySof MA30 intraocular lens (Alcon Laboratories, Ft Worth, Tex) (gr...
INTRODUCTION We report the case of a patient in whom simultaneous toric phakic intraocular lens removal and phacoemulsification with toric intraocular lens implantation were beneficial for reducing pre-existing astigmatism and acquiring good visual outcomes in eyes with implantable collamer lens-induced cataract and astigmatism. CASE PRESENTATION A 53-year-old woman had undergone toric implan...
AIMS We report the case of a myopic patient who, after intraocular lens transplant in the posterior chamber, suffered elevated intraocular pressure due to pigment dispersion, with recurrent episodes of blurred vision. The patient was treated with a new surgical technique that can avoid potential iridolenticular contact. METHODS Complete ophthalmologic examination and optical coherence tomogra...
