Abstract
PURPOSE To compare the efficacy of oral codeine plus acetaminophen versus oxycodone plus acetaminophen for severe pain control following photorefractive keratectomy (PRK). METHODS This single-center trial randomized 200 patients to receive codeine 30 mg/acetaminophen 325 mg (codeine group) or oxycodone 5 mg/acetaminophen 325 mg (oxycodone group)every 4 hours as needed for severe pain for 4 days following PRK. Patients recorded postoperative pain, tablet consumption, and tetracaine use. Patients were monitored at postoperative 1 day, 1 week, and 1, 3, and 6 months for visual acuity and follow-up. Study outcomes were mean postoperative pain, treatment and tetracaine use, and visual acuity. RESULTS Analysis of 197 patients who completed the trial (97 codeine group and 100 oxycodone group) showed mean pain scores were lower in the codeine group throughout the intervention period. Mean pain scores were higher in the oxycodone group than the codeine group on postoperative days 2 and 4 (P = .017 and P = .034, respectively). The oxycodone group consumed more tablets than the codeine group, with a difference on postoperative day 2 (P = .019), and used a greater number of tetracaine drops (P = .015). Repeated measures analysis of variance showed significant improvement in visual acuity in both groups with no difference in visual outcomes (P = .81). CONCLUSIONS Codeine/acetaminophen is as effective and safe as oxycodone/acetaminophen for pain control following PRK, with no clinical difference in overall pain control and long-term visual outcomes. This implies that treating postoperative pain after PRK with a Schedule III opioid (codeine) is effective and potentially decreases the risk of misuse by a higher regulated Schedule II opioid (oxycodone), lowering the potential for abuse and dependence.

Abstract
PURPOSE To define the factors that affect patient's self-assessed postoperative pain after photorefractive keratectomy (PRK). METHODS Patients who underwent PRK in 2016 were evaluated. Anonymized data collected included patient gender, age, and season at the time of surgery, ablation depth, surgeon status (attending vs. resident), topical tetracaine use, and subjective pain scores at postoperative days (PODs) 1 and 7. Average pain scores and amount of pain medication taken were analyzed for each of the previously mentioned variables. RESULTS Overall, 231 patients who underwent PRK were analyzed. The mean pain score and SD were 0.78 ± 1.87 on POD 1 and 0.03 ± 0.37 by POD 7. Patients who used topical tetracaine reported significantly higher pain on POD 1 and 7 compared with patients who did not use tetracaine (P < 0.001 and P = 0.038, respectively). No significant differences in pain scores were seen based on surgeon status, ablation depth, gender, and season. Patients who used topical tetracaine took a higher amount of oral pain medication (9.44 ± 6.01) compared with those who did not (7.02 ± 4.71) (P = 0.022). CONCLUSIONS Postoperative pain was significantly elevated in patients who used tetracaine on POD 1 and POD 7. These patients were also more likely to take oral pain medication than those who did not use topical tetracaine. Surgeon status, season, gender, and ablation depth showed no significant differences in subjective pain scores. Oral pain medication should be evaluated to assess efficacy and safety in inhibiting ocular pain after PRK.

Abstract
INTRODUCTION Pigment dispersion syndrome (PDS) is a condition where anomalous iridozonular contact leads to pigment dispersion throughout the anterior segment and the released pigment is abnormally deposited on various ocular structures. CLINICAL PRESENTATION The clinical presentation of PDS is defined by the presence of pigmented cells on the corneal endothelium, an increase of pigmentation of the trabecular meshwork, and mid-periphery transillumination defects of the iris. This syndrome, more common in myopes, is usually bilateral and can be associated with ocular hypertension or glaucoma. Secondary open-angle pigmentary glaucoma (PG) can develop due to reduction of the outflow of aqueous humour and consequent increase in intraocular pressure leading to glaucomatous optic neuropathy. Diagnosis of PG is commonly between 40 and 50 years of age, occurring more frequently in men. The advent of ultrasound biomicroscopy and anterior segment optical coherence tomography has contributed to enhancing our knowledge on the condition. Typical alterations of the anterior segment are the posterior insertion of the iris and iris concavity. Treatment of PG should be initiated early to hinder disease progression, glaucomatous damage, and vision loss. Management is based on medical therapy, laser iridotomy, selective laser trabeculoplasty, and filtration procedures. CONCLUSIONS The differential diagnosis of PDS with other disorders can be challenging and awareness of the condition together with meticulous ophthalmologic examination allows early diagnosis followed by appropriate management strategies. The present review is a comprehensive report on the clinical characteristics, pathogenesis, current management, and status quo of PDS and PG.

Abstract
Neurofibromatosis type 1, tuberous sclerosis complex, and Von Hippel-Lindau disease, historically classified as the phakomatoses, are hereditary multisystem disorders characterized by the presence of hamartoma, which carry the risk of malignant transformation. The alteration of tumor suppressor genes seems to be at the basis of their pathophysiogenetic mechanism. Lisch and choroidal nodules in neurofibromatosis type 1, retinal astrocytomas in tuberous sclerosis complex, and retinal capillary hemangioma in Von Hippel-Lindau disease are the principal ophthalmic hamartomatous manifestations. The advent of novel imaging techniques such as near infrared reflectance and optical coherence tomography has provided unprecedented insight on the choroidal and retinal features of these diseases. These methods have improved early diagnosis and the ongoing surveillance in these conditions. Among an array of treatment modalities, antivascular endothelial growth factor therapy has been used in the management of retinal hamartomas but results have been varied. This review is an update on the pathophysiogenetic mechanisms, ophthalmic manifestations, and novel treatment strategies in the phakomatoses with emphasis on the role of imaging techniques.

Abstract
PURPOSE To assess the long-term effectiveness and safety of refractive surgery with LASIK or photorefractive keratectomy (PRK) for treating accommodative esotropia in adults. METHODS All patients with accommodative esotropia treated with LASIK or PRK until December 2007 and with a minimum follow-up of 5 years were retrospectively included. RESULTS LASIK was performed on 44 eyes of 22 patients (12 women, 10 men; mean age: 22.7 ± 2.9 years). Mean postoperative follow-up was 62.1 ± 3.2 months. PRK was performed on 16 eyes of 8 patients (4 women, 4 men; mean age: 23.7 ± 1.7 years). Mean postoperative follow-up was 61.3 ± 2.8 months. At the 5-year follow-up, the mean cycloplegic refraction was more hyperopic in the PRK group (0.3 ± 0.8 vs 0.06 ± 0.3 diopters, P = .01). Correction of esotropia to esophoria or orthotropia was present in 21 patients (95.4%) treated with LASIK and in all patients treated with PRK. CONCLUSIONS Both LASIK and PRK were effective in the long-term reduction of accommodative esotropia.

Abstract
PURPOSE To evaluate the clinical results obtained with excimer laser treatment of fully refractive accommodative esotropia. METHODS Fully refractive accommodative esotropia was corrected in 17 patients with laser in situ keratomileusis (LASIK) and in 3 patients with photorefractive keratectomy (PRK). The mean age of the patients at time of refractive surgery was 18.8 years (range 14 to 24 years). All surgical procedures were performed under local anesthesia. The preoperative and postoperative data were retrospectively analyzed with regards to visual acuity, ocular alignment, and stereopsis. RESULTS The mean preoperative deviation without correction was 18.1Delta for near vision and 13.7Delta for distance vision. After refractive surgery the mean postoperative deviation was 4Delta esophoria at near, and 2.5Delta of esophoria at distance: 10 patients (50%) showed esophoria for both distance and near vision, 2 patients (10%) esophoria only for near vision, and 8 patients (40%) orthophoria for both distance and near vision. Emmetropia (-/+1.00 D) was obtained in 97.5% of eyes (39 of 40). The mean correction obtained with excimer laser was +4.62 D(range +2.25 to +7.75, SD 4.52). The preoperative BSCVA was in all eyes greater than or equal to 20/30. There were no significant differences observed between the preoperative and postoperative mean best-corrected visual acuity (p=0.32). There were no complications. The follow-up period lasted a mean of 30.2 months. CONCLUSIONS The treatment of fully refractive accommodative esotropia with excimer laser was found effective and safe, even in young or adolescent patients. More studies are needed to increase the patient experience and extend the follow-up period in order to evaluate the stability of these results over time.

Abstract
Surgical attempts to correct hyperopia have yielded varying results over the last 130 years. These techniques include the reshaping of the cornea through incisions, burns, or lamellar cuts with removal of peripheral tissue; the addition of central inlays; laser ablations; and the replacement of the crystalline lens. By examining the success of each surgical technique, the refractive surgeon may be able to make an informed decision on its indications and limitations, based on the specific patient's characteristics. Reporting the outcomes and complications of hyperopic surgery will help refine our approach to the management of an increasingly hyperopic and presbyopic population.

Abstract
PURPOSE To evaluate photorefractive keratectomy (PRK) followed by bilateral medial rectus muscle recessions (BMR) to treat adults with partly accommodative esotropia. METHODS We reviewed medical records of 10 consecutive patients with partly accommodative esotropia who underwent PRK to correct hyperopia followed 6 months later by BMR to treat the accommodative and nonaccommodative components of their esotropia, respectively. Visual acuity, spherical equivalent of refractive error, alignment, and sensory data were collected and analyzed. RESULTS Twenty eyes of 10 patients were treated and followed for 1 year. PRK was successful in treating the hyperopia (mean post-PRK spherical equivalent was 0.14 D (SD = 0.22)) and the accommodative portion of the esotropia (the mean percentage of the distance accommodative component eliminated by PRK was 101.67% and the mean percentage of the near accommodative component eliminated by PRK was 115%). However, subsequent BMR using standard surgical tables based on the distance deviation to treat the post-PRK residual (nonaccommodative) esotropia resulted in uniform undercorrection. CONCLUSION PRK may be useful to treat the accommodative portion of partly accommodative esotropia. Bilateral medial rectus muscle recession can be used to treat the residual, nonaccommodative component; however, it may be necessary to base the surgical dosage on the near deviation.

Abstract
PURPOSE To study refractive results and aberrometric changes in myopic patients treated with wavefront-guided photorefractive keratectomy (PRK) in comparison with standard PRK. METHODS Sixty eyes of 60 patients with myopic astigmatism were randomly divided into two groups. Group 1 included 30 eyes (mean spherical equivalent refraction -4.39 +/- 1.31 D; range -2.50 to -6.50 D) treated with wavefront-guided PRK using the WASCA workstation and the Asclepion Meditec flying spot MEL 70 excimer laser. Group 2 had 30 eyes (mean spherical equivalent refraction -4.33 +/- 1.22 D; range -2.50 to -6.50 D) that underwent conventional PRK using the same laser, and served as the control group. Wavefront analysis of high order aberrations was performed before and 6 months after surgery. RESULTS Postoperatively, wavefront error increased in both groups (5.0-mm wavefront aperture diameter). Six months after surgery, the eyes that received the WASCA ablation had a smaller increase in root-mean-square (RMS; 70% of increment) compared to the conventional PRK group (139% of increment) (P<.001). In the standard PRK group, all aberrations notably increased; in the wavefront-guided PRK group there was a smaller increase of trefoil and spherical aberrations (P<.001) and a decrease of coma aberrations (P<.001). The smaller increase of wavefront error in the wavefront-guided PRK group compared to the standard PRK group was more evident when preoperative RMS values were higher than 0.4 microm (P<.01). The visual parameters (spherical equivalent refraction, uncorrected and best spectacle-corrected visual acuity) did not show significant differences between the two groups. CONCLUSION Wavefront-guided PRK induced a smaller increase of postoperative wavefront-error compared to conventional PRK, particularly in patients with higher preoperative higher order aberrations.

Abstract
PURPOSE To evaluate the results of photorefractive keratectomy (PRK) for the treatment of young adult patients with purely refractive accommodative esotropia. SETTING Private practice and university hospital, Milan, Italy. METHODS The medical records of consecutive patients who had PRK for hyperopia associated with purely refractive esotropia were reviewed retrospectively. Preoperative and postoperative visual acuity, alignment, and sensory data were recorded and analyzed. Surgical methods and complications were reviewed. RESULTS Sixteen eyes of 8 patients were treated. The mean patient age at the time of treatment was 24.6 years (range 17 to 38 years). All patients were followed for 1 year. At the 1-year follow-up evaluation, the uncorrected visual acuity was 20/40 or better in all eyes. No patient lost a line of best spectacle-corrected visual acuity. The mean spherical equivalent was -3.7 diopters (D) preoperatively and -0.7 D postoperatively. All patients were within +/-0.37 D of emmetropia at the 1-year evaluation. Preoperatively, the mean esotropic deviation was 10.75 prism diopters. Postoperatively, all patients were orthophoric without correction. Stereopsis was unaffected by PRK in all patients. There were no intraoperative or postoperative complications. CONCLUSION Photorefractive keratectomy was an effective treatment for esotropia associated with mild to moderate hyperopia in young adults with purely refractive accommodative esotropia. These findings should not be widely applied to children with accommodative esotropia.
