Automated and subjective refraction with monofocal, multifocal, and EDOF intraocular lenses: review

Abstract

Autorefractor results are reliable in eyes implanted with monofocal IOLs but may be not with mIOL or EDOF IOLs because they can indicate a refractive error that does not clinically exist.

Comment on: Automated and subjective refraction with monofocal, multifocal, and EDOF intraocular lenses: review

“…We read with great interest the article by Bellucci et al, in which the authors described the lack of agreement between automated refraction and subjective refraction across different intraocular lens (IOL) technologies. 1 This observation led to clinically relevant take-home messages which are in complete agreement with our recent review. 2 Among the standout points are the systematic myopic bias of automated refraction and the accuracy of astigmatism measurements.…”

Reply: Automated and subjective refraction with monofocal, multifocal, and EDOF intraocular lenses: review

“…The numerous authors of this communication, numerous because of their respect for Robert H. Osher, were pleased to read his recent exposé on lens cortex. 1 The authors concur that while removal of the cataract nucleus is safe and effective nowadays, even with leathery nuclei, its completion is precisely not the time for the cataract surgeon to heave a great sigh of relief. Despite Professor Osher stating that cortex removal in just a few seconds is "one of the most satisfying steps in cataract surgery," the authors thoroughly agree that this is precisely the time point during the phacoemulsification procedure that requires the greatest vigilance.…”

“…We thank Rodriguez-Vallejo et al for the appreciation for and comments made on our study. 1 They underlined the very purposes of our review that are (1) the importance of considering automated refraction only as a starting point for subjective refraction, (2) the risk of inappropriate evaluation made by ophthalmologists who are unaware of the problem, (3) the risk of inappropriate spectacle or surgical treatment, and (4) the lack of information the surgeons are given about the optics of multifocal and EDOF IOLs. To make the ophthalmology community aware about the problem related to multifocal and EDOF IOLs and automated refraction was our main purpose, and the method suggested by Rodriguez-Vallejo et al provides an excellent and reproducible way to obtain accurate subjective refraction.…”

Comparison between Early Clinical Results of Dual-Linear and Conventional Foot-Pedal Control in Phacoemulsification

“…The field of cataract surgery is one of the most representative areas reflecting cuttingedge technology. State-of-the-art technology is applied to all stages of surgery, including preoperative biometric measurements, intraoperative surgical instruments, intraocular lenses, intraocular lens formulae, the phacoemulsification machine, and postoperative care, including dry eye [3][4][5][6][7][8][9][10][11]. Mechanical and instrumental advancements have shortened the surgical time.…”
