Background and Objective: Ocular surface disease (OSD) is a common yet often overlooked consideration in the management of patients with glaucoma. Although there have been several review articles summarizing the relationship between glaucoma medications and OSD, there is a relative absence of such articles on the effects of glaucoma surgical treatments. Here, we present a comprehensive review of the literature regarding the relationship of glaucoma management and OSD, with an emphasis on surgical considerations.

Methods: PubMed, Google Scholar, and Cochrane Review searches were performed using the following search terms: ocular surface, dry eye, minimally invasive glaucoma surgeries (MIGS), trabeculectomy,glaucoma medications. The titles and abstracts from those searches were screened for relevance to our review topics. Publications were included if the subjects included glaucoma patients, and if ocular surface outcomes were described. Non-English papers were excluded.
Key Content and Findings: Topical glaucoma medications frequently cause adverse effects on the ocular surface, both through direct action of the medications themselves as well as through toxicity from their associated preservatives. Optimization of the ocular surface may improve medication compliance rates.Traditional surgical treatments for glaucoma, such as trabeculectomy, can exacerbate OSD by disrupting the ocular surface but can also reduce the need for chronic medications. Optimization of ocular surface health is imperative in reducing trabeculectomy complication rates, while also potentially reducing the need for trabeculectomy in patients that are able to achieve intraocular pressure control through improved drop tolerability. The introduction of MIGS represents a promising alternative to existing therapies and has been shown to alleviate the overall medication burden. It would be reasonable to assume that decreasing the medication burden could reduce OSD prevalence and severity. However, more research is needed to directly assess the extent of improvement seen after MIGS.

Conclusions: A comprehensive understanding of the importance of OSD in medical and surgical management of glaucoma is essential in optimizing patient care and improving outcomes.

Background: Femtosecond laser astigmatic keratotomy (FSAK) and toric intraocular lens (IOL) implantation have been studied individually for comparison to treat astigmatism at cataract surgery. We report a case of surgically induced high corneal astigmatism by laser thermal keratoplasty (LTK) in a patient with cataract who was successfully treated with simultaneous combination of FSAK and toric IOL implantation with femtosecond laser-assisted cataract surgery (FLACS). This is the first report of both procedures combined simultaneously, with or without history of LTK.

Case Description: A 68-year-old male presented with a history of LTK with two enhancements each eye in 2004, with subsequent surgically induced high corneal astigmatism, and with age-related nuclear cataract of both eyes. IOL master demonstrated +7.71 diopters of astigmatism at 163 degree right eye and +3.29 diopters of astigmatism at 4 degree left eye. After extensive discussion of the risks and benefits, the patient agreed to undergo FLACS with FSAK with two 61 degrees of relaxation incisions (RIs) and toric IOL (Alcon SN6AT9) right eye; FLACS with toric IOL (Alcon SN6AT7) alone left eye. At 2-year follow-up, uncorrected visual acuity was 20/30 right eye, 20/25 left eye. His best corrected visual acuity was 20/25 (+0.25 +1.00 axis 21) right eye and 20/20 (plano +0.25 axis 90) left eye; his best corrected near visual acuity was J1+ with add +2.50 diopters right eye and left eye.

Conclusions: Patients with age-related cataract and LTK induced high corneal astigmatism can hardly be sufficiently treated with FSAK or toric IOL alone at the time of cataract surgery. An effective way is to combine large FSAK and toric IOL of the highest cylindrical power of T9, in our case, simultaneously, which can achieve an excellent long term visual outcome.

Abstract: The goal of ophthalmology residency training is to produce competent ophthalmologists. Appropriate assessments must be employed to ensure this goal is met. Valid and reliable workplace-based assessments are designed to assess competence in the many domains required of a good ophthalmologist. These assessments increase standardization and objectivity as compared to simple observational feedback. When used appropriately, workplace based assessments not only provide measures of competence but also facilitate effective formative feedback and enhance learning.

Abstract: Cataract surgery is arguably the most commonly performed operation in ophthalmology. Surgical skills transfer from experienced surgeons to resident surgeons is complicated by the fact that the teaching surgeon primarily acts as an observer rather than directly performing the procedure. Therefore, wet lab and simulator training are utilized to reduce the learning curve of the novice surgeons, which establishes tissue awareness, dexterity and muscle memory required to perform each step of the procedure, safely. Access to a wet lab and simulator environment is accomplished by establishing a surgical training curriculum in residency programs. In the operating room, topical anesthesia is a safe alternative for teaching cataract surgery. There are three well-described approaches to teaching individual steps of cataract surgery: forward, “backwards”, and deconstructed step-by-step instruction. Simulator training can be incorporated prior to live patient experience or integrated concurrently with learner presence in the operating room. The trend towards a competency-based instruction model has necessitated appropriate evaluation tools that include Objective Assessment of Skills in Intraocular Surgery (OASIS), Global Rating Assessment of Skills in Intraocular Surgery (GRASIS), and the International Council of Ophthalmology’s Ophthalmology Surgical Competency Assessment Rubrics (ICO-OSCAR). We review the literature on trends in surgical teaching in ophthalmology, with the focus on cataract surgery instruction to the novice surgeon.

Abstract: Training qualified ophthalmic professional is crucial for any eye care system worldwide. Education of modern western Ophthalmology in China started late but develops rapidly. This review focused on ophthalmic education in China and US, describing details of the programs and analyzing the differences. This summary may provide useful information for practitioners of medical education from both countries and help improve the present training designs.

Background: To report a new simplified surgical technique to manage small iris coloboma or traumatic iris defect.

Methods: A new surgical technique in which simplified pupilloplasty technique through only a clear corneal paracentesis to manage the iris coloboma or traumatic iris defect within the 120° range was designed. A retrospective revision of the medical records of patients treated with this technique between the years 2013 and 2016 was made. Six eyes of six patients with iris coloboma or traumatic iris defect treated with this new technique were included.

Results: All the operated eyes quickly recovered with central round pupil, negligible complications, inessential symptoms of photophobia and glare, and mild inflammation after a median follow-up time of 22 months (range: 6–34 months).

Conclusions: The simplified pupilloplasty technique presented here could be a good alternative for the management of small iris coloboma or traumatic iris defect.

Background: To evaluate efficacy and safety of combined pars plana vitrectomy (PPV) and scleral fixated intraocular lens (SFIOL) surgery as a single procedure.

Methods: Retrospective interventional case series done at a tertiary eye care center in Northern India. Eleven patients who underwent combined PPV and SFIOL surgery were included and analyzed retrospectively.

Results: Mean age of the patients was 43.36±15.12 years (range, 22–64 years). Eight were male. Mean baseline best corrected visual acuity (BCVA) was 0.78±0.63 logMAR units while the mean post-operative BCVA at 6 months follow-up was 0.37±0.29 logMAR units, the visual gain being statistically significant (P=0.021). None of the patients had a drop in BCVA with nine patients having final BCVA better than 0.48 logMAR units. Choroidal detachment (CD) was the only notable complication, seen in three patients. Other complications included two cases of intraoperative retinal breaks, a case each of reversible corneal edema, ocular hypertension and cystoid macular edema.

Conclusions: Combined PPV and SFIOL is an efficacious procedure for managing IOL/lens dislocation and aphakia in a single surgery. There may be short-term reversible complications with no impact on final visual gain.
