“…(2) Accommodation demand was increased at the early postoperative period because of post apex moved backward to cornea and overcorrection early postoperatively. 26 In our study, the decline in the AA had a significant positive correlation with the increase in the CT. Previous studies speculated that in the absence of a clear retinal image, ocular accommodation was stimulated.…”

Purpose To investigate early changes in choroidal thickness (CT) and the relationship with accommodation after myopic excimer laser surgery. Methods We enrolled the right eye of 70 patients with myopia and without other ophthalmic or systemic diseases who were suitable for myopic excimer laser surgery. The CT was measured at the fovea and at distances of 0.5 and 2.5 mm for the following: nasal; temporal; superior; and inferior to the fovea preoperatively and at 1 month postoperatively. Other data collected included demographic information (age, sex, and refractive error), the amplitude of accommodation (AA), intraocular pressure, axial length, corneal thickness, and surgical parameters. The data were analyzed with a paired Student's t-test, stepwise linear regression, and correlation analysis. Results The CT was significantly thicker postoperatively compared with the preoperative CT. The AA significantly decreased postoperatively. The change in the AA was the most significant factor associated with the change in the CT at the fovea. Except for 2.5 mm inferior to the fovea, the increase in the CT at other locations was positively correlated with the decrease in the AA. Conclusions The CT increased following myopic excimer laser surgery and the change was most obvious when accompanied by a decrease in the AA early after the surgery.

“…Docking of the eye into the LASIK interface is known to cause a significant rise in intraocular pressure, in the order of Z80 mm Hg. 17,18 Although this has been linked to complications such as LASIK-induced optic neuropathy, 19 it is generally well tolerated by the younger refractive surgery population. 10 However, this rise in intraocular pressure is likely to be more problematic in elderly cataract patients, with the risk of ischaemic retinal and optic nerve injury.…”

Femtosecond laser-assisted cataract surgery (FLACS) represents a potential paradigm shift in cataract surgery, but it is not without controversy. Advocates of the technology herald FLACS as a revolution that promises superior outcomes and an improved safety profile for patients. Conversely, detractors point to the large financial costs involved and claim that similar results are achievable with conventional small-incision phacoemulsification. This review provides a balanced and comprehensive account of the development of FLACS since its inception. It explains the physiology and mechanics underlying the technology, and critically reviews the outcomes and implications of initial studies. The benefits and limitations of using femtosecond laser accuracy to create corneal incisions, anterior capsulotomy, and lens fragmentation are explored, with reference to the main platforms, which currently offer FLACS. Economic considerations are discussed, in addition to the practicalities associated with the implementation of FLACS in a healthcare setting. The influence on surgical training and skills is considered and possible future applications of the technology introduced. While in its infancy, FLACS sets out the exciting possibility of a new level of precision in cataract surgery. However, further work in the form of large scale, phase 3 randomised controlled trials are required to demonstrate whether its theoretical benefits are significant in practice and worthy of the necessary huge financial investment and system overhaul. Whether it gains widespread acceptance is likely to be influenced by a complex interplay of scientific and socio-economic factors in years to come.

Optic neuropathy associated with laser in situ keratomileusis

Abstract: Patients who have LASIK may experience an acute anterior or retrobulbar optic neuropathy. The etiology is unknown but may be related to the marked increase in intraocular pressure that occurs during a portion of the procedure.
