Abstract:

Aim: The aim of this study was to evaluate the possibility and effectiveness of reaching 20/20 uncorrected visual acuity after refractive surgery in patients treated with anterior lamellar keratoplasty for keratoconus, as part of their full visual recovery.

Method: This is a retrospective review of 30 patients (22 eyes) treated with automated lamellar keratoplasty for moderate to severe keratoconus. One year after surgery, suture removal was completed and refractive surgery (LASEK) was evaluated for them to depend less on glasses or contact lenses. All surgeries were done by a single surgeon.

Results: After automated lamellar keratoplasty, all 22 eyes restored normal thickness and acceptable curvature improving uncorrected and best corrected visual acuity compare to before surgery. All 30 patients were candidates for refractive surgery LASEK which was performed with no complications. Final uncorrected visual acuity after three months was: 17 eyes (77.2%) 20/20, two eyes (9.9%) 20/25, One eye (4.5%) 20/30 and two eyes (9.09%) 20/40.

Conclusion: Refractive surgery in its variant of LASEK is a very useful and safe procedure to remove post lamellar keratoplasty refractive errors. It is limited to the amount of degree to treat and other procedures such as LASIK or phakic IOL insertions are possibly good alternatives. All patients operated bilaterally were able to develop their normal life activities depending less on glasses and started doing sport activities that previously were impossible.

Abstract:

Here, we report the case of a patient who underwent Nd:YAG treatment of macular hemorrhage in Valsalva retinopathy with a persistent ILM unsealed after Nd:YAG membranotomy. The Valsalva maneuver was named after the Italian anatomist Antonio Maria Valsalva (1666-1723), who defined the Valsalva ligaments and anatomy related to the forced exhalation effort against a glottis. The Valsalva retinopathy usually appears as a pre-macular hemorrhage limited, but its exact anatomical location, subMLI or subialoide, is still controversial and difficult to define by ophthalmoscopy. The Valsalva retinopathy occurs in healthy young adults as a result of weight lifting, constipation (Stretching the toilet), vomiting, cough (asthma), sneezing, work, airbag automobile trauma related, vigorous sexual activity, dance vigorous, bungee jumping, comprehensive injury and is also associated with fiber optic gastroenteroscopy. Creating a sudden increase in intra-thoracic and intra-abdominal pressure can cause a rapid increase in venous pressure with spontaneous rupture of capillaries perifoveal retina (Valsalva retinopathy), leading to a sudden and painless loss of vision. The low cost outpatient procedure is relatively safe and results in faster recovery as well as in good visual results in most patients with Valsalva retinopathy. Previous studies have shown that, in patients with acute premacular hemorrhage, the Nd: YAG membranotomy must be performed within the first three weeks to avoid the failure of blood draining into the vitreous. In our case, there was a persistent ILM unsealed after the Nd: YAG membranotomy, as demonstrated by tracking Optical Coherence Tomography (OCT).

Abstract:

In this study, a 51 year-old-patient with double corneal transplant in right eye was studied. First corneal transplant was done in 1999 and she never got vision. Second corneal transplant was done in 2010. After a year, there was considerable deformation in the corneal tissue and the cornea became totally leukomatous, deformed and irregular and the eyeball descended to lower eyelid (keratoglobe). I met the patient with ophthalmologist diagnosis of eyeball evisceration. The patient was in deep depression. Due to the irregular and deformed cornea, neither an ocular prosthesis nor soft prosthetic lens could be adapted. So I tried with a scleral lens. In the first test, the general condition of her irregular cornea improved considerably, permitting a good tear film flow between the cornea and the lens. I checked again her cornea and there was neither vision nor light reflection. I consulted the director of scleral lenses for perfect vision in Chile and suggested using a double flap over the lens. Thus, the landing in the sclera was improved and was not ejected. I adapted a scleral lens X-cel Atlantis, base curve 7.50, diameter 17.5 double flap. I put a soft lens painted with black pupil and then a second scleral lens with the same parameters, with perfect adhesion. The patient felt very comfortable, with improved quality of life, could insert herself at work again and now her life has completely changed for the better.

Abstract:

Vitreoretinal surgery has far advanced since the last decades, coming to a modern area of both vitrectomy and viewing systems, as well as with better approaches from the retinal surgeon, with the use of smaller gauge instruments, making the procedure easier to perform, thus contributing to a better follow up and recovery from the surgery. Though repairing techniques have changed, scleral buckling techniques are still popular since Charles Schepens’ techniques in the early 1950s. Combined approaches are still largely employed, increasing the likelihood of attaching the retina, such as pars plana vitrectomy and scleral buckling procedures, with laser or cryotherapy, the last one mentioned less used due to disadvantages involving retinal pigment epithelium spreading and proliferative vitreoretinopathy, but not counter indicated though. Even though the cost and equipment involving vitrectomies are higher than those of scleral buckling alone, the anatomical results are proved to be faster with both approaches rather than with just one. Scleral buckling techniques, even though used in a lesser extent, still have the indication especially in the phakic patient. For the pseudophakic or aphakic patient, some buckle techniques or modified and combined buckle and vitrectomy techniques are used, such as using a band together with vitrectomy to help increase the likelihood the retina will attach during and after the procedure is made. Vitreoretinal surgery used to take too long before the development of wide angle vitrectomy viewing systems. Before it, prisms lenses had to be rotated for the aim of viewing the far periphery, and the contact lens often times had to be held with a ring on the cornea. With the advent of 23 gauge vitrectomy, 25 and 27 came afterwards and are far more used nowadays, and benefits are linked to better success rates. Intraoperative Optical Coherence Tomography assisted vitrectomies, despite expensive, are helping treat macular diseases as well as other vitreoretinopathies, giving a simultaneous visualization of the procedure of the actual surgical record comparing with the topographical cut making it more accurate to approach the retina and expecting better outcomes. Magnifying lenses and inverting image systems are applied in the management of manage macular diseases such as macular holes, epiretinal membranes and others such as proliferative vitreoretinopathy. The use of gas or silicon oils increased overtime, as well as fluorocarbon liquids, playing a very important role not only in repairing retinal detachments, but also helping the surgeon control better hard and demanding cases. Conclusions: We conclude that such a combined approach to primary pseudophakic and aphakic retinal detachments offers significant benefits to scleral buckling alone. We believe that the improved success rate is a function of vitrectomy contributing to both an improved peripheral visibility, resulting in fewer missed peripheral breaks, and a lower likelihood of proliferative vitreoretinopathy. We recommend this combined surgical approach for all primary pseudophakic and aphakic retinal detachments. We conclude that such a combined approach to primary pseudophakic and aphakic retinal detachments offers significant benefits to scleral buckling alone. We believe that the improved success rate is a function of vitrectomy contributing to both an improved peripheral visibility, resulting in fewer missed peripheral breaks, and a lower likelihood of proliferative vitreoretinopathy. We recommend this combined surgical approach for all primary pseudophakic and aphakic retinal detachments. Also, smaller gauge vitrectomies and wide angle vitrectomy viewing systems help manage tough cases with less time and better outcome, making it feasible and more cost effective in today’s vitreoretinal surgery techniques.

Abstract:

Aim: Aim of this study is to determine the clinical benefits of intense-pulsed-light therapy for the treatment of dry-eye disease due to meibomian gland dysfunction.

Method: A retrospective non-comparative interventional case series was conducted on 91 patients presenting with severe dry eye syndrome (eligibility tear breakup time less than 10 seconds or patient referral). Treatment included intense-pulsed-light therapy and gland expression at a single outpatient clinic over a 30-month study period beginning from May 2009. Pre/post tear breakup time data were available for a subset of 78 patients. For all patients, a specially-developed technique for the treatment of dry eye syndrome was applied as a series of monthly treatments until adequate improvement in dry eye syndrome symptoms by physician-judgment or patient-discontinuation.

Results: Primary outcomes included change in tear breakup time by oculus non-invasive or by standard invasive using fluorescein methods, self-reported patient satisfaction, and adverse events. Physician-judged improvement in dry-eye tear breakup time were found for 68 of 78 (87%) patients with seven treatment visits and four maintenance visits on average (medians). 93% of patients reported post-treatment satisfaction with dry eye syndrome symptoms. Adverse events, most typically redness or swelling, were found for 13% of patients. No serious adverse events were found.

Conclusions: While preliminary, study results of intense-pulsed-light therapy treatment for dry eye syndrome due to meibomian gland dysfunction are promising. A multi-site clinical trial with a larger sample, treatment comparison groups and randomized controlled trials is currently underway.

Abstract:

We report a patient with lattice corneal dystrophy Type I with preoperative BCVA CF @ 4 feet OS with dense posterior sub capsular cataract left eye. Patient had phacoemulsification cataract surgery with intraocular lens implant and at one-month post-operative exam had BCVA 20/30.  To our knowledge, this is the first reported successful case of cataract surgery in patient with lattice corneal dystrophy without complications such as corneal melt as reported in a case report of a patient with Lattice Corneal Dystrophy type II.

Lattice corneal dystrophy is a non-inflammatory, autosomal non-dominant, bilateral condition that involves morphologic changes in the corneal stroma.  Visual impairments associated with stromal corneal dystrophies vary widely and are determined by the amount of deposits accumulated in the cornea.  Haziness is a result of the irregular corneal surface that induces blurry vision to the patient.  Recurrent erosions, corneal melt, and prolonged healing area some of the potential risk in patient with lattice corneal dystrophy after cataract surgery.

Abstract:

Over the last few years, more companies are spending more research dollars in developing new medications for dry eye disease (DED). We have completed and have several on going studies on different drops specifically designed for DED. Recently a medication, lifitegrast was approved. Lifitegrast is an anti-inflammatory drop that inhibits the binding of LFA-1 to ICAM-1 down-regulating the inflammation mediated by T lymphocytes. It is the only medication FDA approved for the signs and symptoms of DED. We will present FDA and our current research of this novel drop. We will also cover our work with platelet rich plasma eye drops, optimel, and oculocin. All work will include OSDI data, TBUT, and effects on lid margin disease.

Abstract:

It is the only defense weapon that the human body's immune system has. Over 90% of illnesses appear when this becomes unbalanced, and even if not compensated on time, treatments for restoring health becomes longer and not the desired short term results, with high risk of recurrent clinical pictures. This gift of nature is received by each of those who have reached a pregnancy to term, and fed maternal colostrum and full breastfeeding because it is the only way of passing from mother to son and so complete mature system immature immune with which we are born, if pregnancy is not terminated, the mother does not produce maternal colostrum containing transfer factors that help to strengthen and complete the child's immune system. If a mother does not give breastfeeding to her newborn child and the baby is powered by formula, the newborn does not receive transfer factors included in maternal colostrum and certainly his immune system is not strengthened, being unprotected. Children, who have not completed the maturation of their immune system, suffer from many disorders ranging from constant colds, irritability, recurrent allergic processes, hyperactivity, slow to heal pathological processes and quickly falling in recurring pictures, turning to a vicious circle. A regular event in pediatric patients is the alteration of the ocular optical system, which can be associated or not to the alteration of the neuromuscular system, and if we have a hyperactive patient with disorder of the physiological system and if also suffering from ametropia, hyperopic undoubtedly that the symptoms presented by the patient is aggravated. Taking into consideration of this perspective, certainly we have to consider in our history orientation to seek information about the mode of delivery and initial feeding of the pediatric patient, as it would give us valuable information about the comprehensive patient health.

Abstract:

Many eye surgeons are extremely competent in Phacoemulsification. Many others are competent in trabeculectomy and many are not competent in both the surgeries. But to manage a patient having cataract plus open angle glaucoma simultaneously, an eye surgeon needs to develop the skill of combined surgery i.e. phacoemulsification plus trabeculectomy in the same surgical setting. In this video based presentation, combined surgery will be demonstrated with emphasis on releasable sutures to control IOP postoperatively.

Abstract:

The fitting of RGP contact lenses provides a gain in visual acuity of the patient that presents irregularities in the cornea, but these irregularities, such as a fingerprint, are different for each individual, so that the standard trial sets cannot cover all cases. The purpose of the presentation is to show how changes on the test lenses can bring results for the patient.

Method:

For example, when setting the refractive index for back surface toric lenses adjust the specific weight and change the asphericity.

Conclusion:

It is possible to achieve a good fitting with hard work and some concepts. Use specific gravity and refraction index to go up or go down the contact lenses, use refraction index near to the tear index to minimize induced astigmatism and more or less asphericity to adjust the lens on the cornea.
