Dr. Matt Feng, MD moderates this journal club with Dr. Ian Morgan discussing the article "Myopia Control Effect of Repeated Low-Level Red-Light Therapy in Chinese Children."

In this video, Dr. Amar Agarwal details several cases in which complications occurred involving pinhole pupilloplasty.

In post-refractive surgery eyes, we come across irregular corneas that can be a source of disturbing symptoms, like glare and haloes. These symptoms are accentuated when the patient develops cataract, making planning for cataract surgery a difficult task.

The 3Z application was developed for accurate Contoura Vision surgery planning, for optimal outcome in complex cases where there is a mismatch between Topolyzer and manifest refraction using an inbuilt artificial intelligence (AI) algorithm that was computed using experience…

In this presentation from the AGS 2020, Dr. Salim describes how glaucoma patients may benefit from refractive surgery and highlights important surgical considerations glaucoma specialists should consider when monitoring these patients.

The safety and efficacy of topography-guided PRK (tPRK) treatments after Descemet-stripping automated endothelial keratoplasty (DSAEK) will be demonstrated in cases that underwent tPRK 8-18 months following DSAEK.

This video discusses the use of medical contact lenses, corneal crosslinking, refractive surgery, and selective corneal transplantation in pediatric patients.

We describe the surgical technique of small-incision lenticule extraction (SMILE), with tips to facilitate easy lenticule dissection and extraction.

Ectasia following refractive surgery is a dreaded complication that is poorly understood and hence often undetected.

Although small-incision lenticule extraction (SMILE) is safe overall, certain complications unique to SMILE can be encountered.

Presbyopic allogenic refractive lenticule is a new technique to treat presbyopia using the small-incision lenticule extraction (SMILE).

In this presentation from AAO 2016, Thomas Kohnen, MD, discusses 3 trifocal IOLs: the Zeiss Trifocal AT LISA, the AcrySof IQ PanOptix, and the FineVision Trifocal.

In this presentatation from AAO 2016, Eric D. Donnenfeld, MD, discusses the newest technology and the latest techniques affecting cataract surgery around the world but not in the US.

Discussion includes causes of ametropia, evaluation of the postoperative patient, residual ametropia, mixed astigmatism, limbal relaxing incisions (LRIs), astigmatism correction when spherical equivalent is off, laser vision correction (LVC) to treat ametropia, Nd:YAG poster…

A basic toric intraocular lens (IOL) calculation includes verifying regular, symmetric astigmatism; identifying the steep meridian; determining the power difference between principal meridians; and including surgically induced astigmatism. Dr. Warren Hill discusses advances…

The odds ratio and relative risks of ectasia after LASIK are discussed. Statistics are from a patient population of 184,728 (361,848 eyes) who underwent LASIK between January 3, 2007, and April 30, 2011.

It is estimated that about 70% of eyes undergoing cataract surgery will postoperatively be within ±0.5 D of the targeted refraction. It's a different story with eyes that earlier have undergone keratorefractive procedures, and that often poses a problem for precise IOL power…

Any compromise in tear film integrity can result in IOL calculation errors, topographic abnormalities, and higher-order aberrations. There are incredible tools to create quality vision from the inside, but a perfect 20% is still not enough when a higher yield can come from o…

Prevalence of greater than 1 D of residual astigmatism after toric IOL implantation has been estimated to be 12%.

This video discusses the accuracy of intraoperative aberrometry in predicting postoperative astigmatism in patients undergoing cataract surgery.

This video asserts that placido-based ectasia is an essential adjunct to accurate ectasia detection and can help with recognition of early ectasia that might be less evident using elevation based technology.

This video evaluates Scheimpflug measurements in distinguishing highly asymmetric keratoconus from normal corneas by using a comparative analysis of Pentacam HR analysis of the forme fruste eye with normal controls.

Dr. Yoo discusses the management of postkeratoplasty astigmatism, a common cause of poor visual outcomes despite clear grafts.

This video reviews current and upcoming devices in intraoperative guidance, including both intraoperative abberometry and image guidance systems used during surgery.

Dr. Sayegh presents design principles of a universal IOL calculator capable of simultaneously handling spherical, toric, and postrefractive surgery cases.
