History of Refractive Surgery
History of Refractive Surgery Refractive surgery corrects common vision problems by reshaping the cornea, the eye’s outermost layer, to bend light rays to focus on the retina, reducing an individual’s dependence on eye glasses or contact lenses.1 LASIK, or laser-assisted in situ keratomileusis, is the most commonly performed refractive surgery to treat myopia, hyperopia and astigmatism.1 The first refractive surgeries were said to be the removal of cataracts – the clouding of the lens in the eye – in ancient Greece.2 1850s The first lensectomy is performed to remove the lens 1996 Clinical trials for LASIK begin and are approved by the of the eye to correct myopia.2 Food & Drug Administration (FDA).3 Late 19th 2 Abott Medical Optics receives FDA approval for the first Century The first surgery to correct astigmatism takes place. 2001 femtosecond laser, the IntraLase® FS Laser.3 The laser is used to create a circular, hinged flap in the cornea, which allows the surgeon access to the tissue affecting the eye’s 1978 Radial Keratotomy is introduced by Svyatoslov Fyodorov shape.1 in the U.S. The procedure involves making a number of incisions in the cornea to change its shape and 2002 The STAR S4 IR® Laser is introduced.

This Is a Program Where Learning Is Valued and the Educational Experience Is Tangible
“This is a program where learning is valued and the educational experience is tangible. You will learn a vocation, but it differs from many other schools in that HMS is a very academic environment. This is a place where a trainee can approach a faculty member and count on getting help.

Ocular Surface Changes Associated with Ophthalmic Surgery
Journal of Clinical Medicine Review Ocular Surface Changes Associated with Ophthalmic Surgery Lina Mikalauskiene 1, Andrzej Grzybowski 2,3 and Reda Zemaitiene 1,* 1 Department of Ophthalmology, Medical Academy, Lithuanian University of Health Sciences, 44037 Kaunas, Lithuania; [email protected] 2 Department of Ophthalmology, University of Warmia and Mazury, 10719 Olsztyn, Poland; [email protected] 3 Institute for Research in Ophthalmology, Foundation for Ophthalmology Development, 61553 Poznan, Poland * Correspondence: [email protected] Abstract: Dry eye disease causes ocular discomfort and visual disturbances. Older adults are at a higher risk of developing dry eye disease as well as needing for ophthalmic surgery. Anterior segment surgery may induce or worsen existing dry eye symptoms usually for a short-term period. Despite good visual outcomes, ocular surface dysfunction can significantly affect quality of life and, therefore, lower a patient’s satisfaction with ophthalmic surgery. Preoperative dry eye disease, factors during surgery and postoperative treatment may all contribute to ocular surface dysfunction and its severity. We reviewed relevant articles from 2010 through to 2021 using keywords “cataract surgery”, ”phacoemulsification”, ”refractive surgery”, ”trabeculectomy”, ”vitrectomy” in combina- tion with ”ocular surface dysfunction”, “dry eye disease”, and analyzed studies on dry eye disease pathophysiology and the impact of anterior segment surgery on the ocular surface.

Effects of Depth of Incision on Final Outcome in Radial Keratotomy N
Effects of Depth of Incision on final outcome in Radial Keratotomy N. Raja, M. K. Niazi B-35, PAF Complex, Sector E-9, Islamabad. Abstract Objective: To assess the effect of depth of incision on the final outcome of radial keratotomy for correction of myopia. Methods: Sixty-five eyes with preoperative uncorrected myopia between 2.5-6.0D in subjects with a mean age of 29.2 (+7) years underwent radial keratotomy between Sept 1999--July 2002 in department of Ophthalmology, Military Hospital, Rawalpindi. Based on their preoperative depth of incision the eyes were divided into group-A (twenty-five eyes), with an incision depth of 500-530 µm, and Group-B (forty eyes), with an incision depth of 531- 560 µm. The comparison between the postoperative visual acuity of two groups was made at the end of study after one years` follow up. Results: A total of Sixteen eyes in Group-A (64%) that were within one diopter of emmetropia at first follow-up reverted back to their preoperative myopic state after one year of surgery as compared to only two eyes (5%) in Group-B (p<0.05). Hyperopic shift occurred in two eyes (8%) in Group-A, as compared to four eyes (10%) of Group-B (p >0.05). After one year, refraction showed that only 24% cases of Group-A were within 1 diopter of emmetropia as compared to 85% cases in Group-B. Similarly, 40% cases of Group-A were within 2 diopters of emmetropia as compared to 90% cases of Group-B. Glare and variation of vision in the initial four weeks were the most frequently reported complications in both groups. -

The patient has had progressive visual field deterioration on maximum tolerated medications, and pressures in the high teens with a diagnosis of uncontrolled open angle glaucoma, left eye. To preserve her visual field, it was felt that surgery was necessarygiven the extensive damage to her optic nerve and field already existing |3|. The risks, benefits, and alternatives to surgery were discussed with the patient as well as with her husband, and she was anxious to proceed. PROCEDURE: The patient was brought to the operating room where she was given an intravenous sedative and peribulbar block. She was then prepped and draped in customary sterile fashion for intraocular surgery. A wire lid speculum was placed, and a 6-0 Vicryl traction suture was put through the superior peripheral cornea. The globe was retracted downward. The conjunctiva was entered 12 mm proximal to the limbus. With a combination of blunt and sharp dissection it was dissected down to the surgical limbus. The Gill’s knife was used to bare the limbus, and hemostasis was achieved with bipolar cautery |4|.

All blebs were imaged with 3D AS-OCT and analyzed with our custom software. We assessed blebs quantitatively for the following features: bleb height, fluid-filled cavity height, bleb wall thickness, and bleb wall intensity. Results: The mean (± standard deviation [SD]) time period between trabeculectomy and 3D AS-OCT measurement was 9.5 ± 6.2 months; the mean (±SD) intraocular pressure (IOP) measured 14.0 ± 4.3 mm Hg at the time of 3D AS-OCT imaging. IOP and the bleb height (rs = -0.609, P = < .0001), the fluid-filled cavity height (rs = -0.381, P = 0.009), the bleb wall thickness (rs = -0.503, P = 0.0004) and the bleb wall intensity (rs = 0.612, P = < .0001) showed statistically significant correlations. -
