BACKGROUND AND OBJECTIVE: The authors describe a modified surgical technique for Argus II retinal prosthesis implantation. PATIENTS AND METHODS: The modified surgical technique was performed in a 43-year-old male with retinitis pigmentosa (RP) who underwent strabismus surgery in that eye at age 8. RESULTS: During Argus II implantation, the lateral rectus (LR) was noted to be 10 mm posterior to its original insertion due to prior strabismus surgery...

REVIEW
Jed Lusthaus, Ivan Goldberg
Glaucoma is an irreversible progressive optic neuropathy, for which the major proven treatment is to lower the intraocular pressure (IOP). Five groups of IOP-lowering eye drops have varying mechanisms of action. Some drops, such as β-blockers and α-2 agonists, have potentially serious systemic side effects. Acetazolamide is the only available oral agent; it is effective at lowering IOP, but significant side effects relegate its use usually to refractory glaucoma. Two new eye drops, netarsudil and latanoprostene bunod, have recently been approved by the United States Food and Drug Administration...

REVIEW
Magdalena Jędzierowska, Robert Koprowski
BACKGROUND: Non-contact tonometers based on the method using air puff and Scheimpflug's fast camera are one of the latest devices allowing the measurement of intraocular pressure and additional biomechanical parameters of the cornea. Biomechanical features significantly affect changes in intraocular pressure values, as well as their changes, may indicate the possibility of corneal ectasia. This work presents the latest and already known biomechanical parameters available in the new offered software...

PURPOSE: To assess the outcomes of micropulse transscleral cyclophotocoagulation for intraocular pressure (IOP) control in keratoplasty eyes. METHODS: Outcomes of micropulse laser treatments of postkeratoplasty eyes were retrospectively reviewed. IOP was assessed with applanation tonometry. Keratoplasty survival was calculated with Kaplan-Meier survival analysis. RESULTS: Sixty-one eyes in 57 patients received laser treatment; 31 eyes received 1, 21 received 2, 8 received 3, and 1 received 4 treatments...

PURPOSE: To analyze the positional relationships of various centers in patients undergoing femtosecond laser-assisted cataract surgery (FLACS). METHODS: The locations of the pupil center (PC), limbal center (LC) and lens center were analyzed in each patient using optical coherence tomography during FLACS in 35 eyes of 35 patients. Using the preoperative corneal aberrometry device, angle kappa and the location of the visual axis (VA) were calculated. After acquiring the relative horizontal and vertical coordinates of each center, the distance and location among each center were compared...

This paper presents techniques for robot-aided intraocular surgery using monocular vision in order to overcome erroneous stereo reconstruction in an intact eye. We propose a new retinal surface estimation method based on a structured-light approach. A handheld robot known as the Micron enables automatic scanning of a laser probe, creating projected beam patterns on the retinal surface. Geometric analysis of the patterns then allows planar reconstruction of the surface. To realize automated surgery in an intact eye, monocular hybrid visual servoing is accomplished through a scheme that incorporates surface reconstruction and partitioned visual servoing...

Purpose: To assess the efficacy of applying bandage contact lens (BCL) in reducing the fibrotic healing response of flap margins following femtosecond laser in situ keratomileusis (FS-LASIK). Methods: In this prospective, randomized, interventional, observer-masked trial, 41 patients (82 eyes) with myopia and/or myopic astigmatism were scheduled to undergo FS-LASIK. After surgery, patients were fitted with a BCL in one eye (BCL eyes, n =41) but not in the contralateral eye (control eyes, n =41), following randomized allocation of the BCL to the left or right eye of each patient...

Previous studies compared ocular aberration and visual quality after small-incision lenticule extraction (SMILE) and Q value-guided femtosecond laser-assisted in situ keratomileusis (Q-FS-LASIK), but anterior corneal surface aberration properties are poorly known. This study aimed to compare the changes in anterior corneal surface aberration after SMILE versus Q-FS-LASIK.This was a prospective, observational cohort study. Patients with myopia and myopic astigmatism underwent SMILE or Q-FS-LASIK at Hangzhou MSK Eye Hospital between January 2015 and November 2015...
