For example, femtosecond laser technology emerged after fifty years of employing laser technology in ophthalmology .Theodor Scheimpflug described the principle of scheimpflug images in 1904 , but he was actually an Austrian army captain who spent his life’s work dedicated to designing methods and tools to create maps depicting aerial photography .
Patients with a history of corneal refractive surgery expect reduced dependence on spectacles after cataract surgery.Surgeons altered cylindrical power 24% of the time and spherical power 35% of the time.Patients were 2.4 times more likely to have less than 0.50 D of residual refractive astigmatism when intraoperative aberrometry was used . published a study where aphakic spherical equivalent- (SE-) based IOL formulas were generated from repeated intraoperative wavefront aphakic measurements of SE.Application of these principles to ophthalmology in the last few years has advanced our understanding of corneal biomechanics .The latest highlights in technology include advances in preoperative and intraoperative diagnostics, femtosecond laser-assisted cataract surgery (FLACS), and a new generation of intraocular lenses (IOLs).With cataract surgery regarded as the most widely performed surgical procedure, a demand exists for continued innovation and technology.
The latest advances evolved through application of well-defined principles to current surgical goals and patient expectations.The Acutarget HD (Visiometrics SL, Spain) uses a double pass system to measure point spread function (PSF), modulation transfer function (MTF), Strehl ratio, and intraocular scattering of the light.These data allow clinicians to evaluate the quality of a patient’s optical system objectively .The Tear Lab Osmolarity System (Tear Lab Corporation, San Diego, California) uses a small tear sample to measure tear osmolarity using a microelectrode.Compared to other commonly used diagnostic tests for dry eye disease, test results were better at predicting dry eye severity .The Lipiflow (Tear Science, Morrisville, North Carolina) combines heat and eyelid pressure to treat dry eye disease due to meibomian gland dysfunction.
