RESUMEN
PURPOSE: To examine the long-term effect of combined blepharoplasty and Müller muscle-conjunctival resection (MMCR) compared to an upper blepharoplasty procedure on dry eye syndrome. METHODS: This is a Prospective comparative case series. Two groups of patients participated in this study: the blepharoplasty group included adult patients that underwent blepharoplasty at least 3 years earlier and the ptosis group consisting of adult patients that underwent MMCR with blepharoplasty at least 3 years earlier. The parameters that were compared for all patients before the procedure, on postoperative day 90, and at the long-term follow-up were: Schirmer-test 2, tear break-up time (TBUT), fluorescein staining, and lissamine green (LG) staining. RESULTS: The participants included 25 post-MMCR patients with a mean follow-up of 4.94 ± 0.64 years and 15 post-blepharoplasty patients with a mean follow-up of 4.22 ± 0.32 years. There was a significant increase in the postoperative LG and fluorescein staining scores compared to the preoperative scores in the ptosis group (p < .01 and p < .01, respectively) as well as a decrease in postoperative TBUT compared to the preoperative values (p = .044). Those parameters were not significant in the blepharoplasty group. CONCLUSIONS: Patients who underwent MMCR, but not those following upper blepharoplasty, showed signs of dry eye compared to the preoperative status after long-term follow-up. Dry eye signs should be examined before MMCR surgery, and patients should be aware of the high risk of developing dry eye and the need for long-term treatment. Surgeons should carefully consider performing MMCR for patients with severe dry eye.

BACKGROUND: This study aimed to evaluate the impact of PreserFlo Microshunt on the ocular surface, focusing on both objective and subjective parameters. METHODS: Prospective-observational study on 48 eyes undergoing PreserFlo Microshunt implantation, standalone or combined with phacoemulsification. At baseline, 1-month, 6-months and 12-months post-operative follow-ups, we performed Ocular Surface Disease Index (OSDI) questionnaire, Schirmer's test (ST), Tear-film break-up time (TBUT), fluoresceine staining (FS), tear osmolarity and minimum corneal epithelial thickness (Epi-ThkMIN. ) measurements. RESULTS: OSDI score improved from 37.43 ± 17.49 at baseline, to 24.13 ± 12.55 at 1-month (p = 0.003) and to 12.89 ± 8.54 and 13.09 ± 10.22 at 6-months and 12-months (p < 0.0001). TBUT and ST, in a similar way, non-significantly increased at 1-month, but then improved at 6-months and 12-months (p < 0.05 for both). Tear osmolarity significantly decreased from 308.2 ± 7.3 mOsm/L at baseline, to 303.3 ± 8.2 mOsm/L, 295.6.2 ± 7.0 mOsm/L and 297.6 ± 6.8 mOsm/L at 1-month, 6-months and 12-months (p < 0.05 for all). Epi-ThkMIN was stable when comparing baseline (44.9 ± 5.7 µm) and 1-month (p = 0.28), and successively increased in 6-months (47.8 ± 5.5 µm, p = 0.02) and 12-months (48.0 ± 3.6 µm, p = 0.01). In subgroup analysis, OSDI score and tear osmolarity were significantly higher at 1-month in combined group compared to standalone group (p = 0.03 and p = 0.02, respectively), but reaching comparable values in successive follow-ups. Further, Oxford scale grades for FS were significantly improved when comparing baseline-6-months and baseline-12-months. CONCLUSION: PreserFlo implantation improved ocular surface subjective symptoms, increased TBUT and ST, and reduced FS, highlighting the potential benefits of this surgical intervention. Moreover, we reported significant improvements of tear osmolarity and corneal epithelium.

The medical treatment of dry eye disease usually follows a step-wise approach to achieve clinical improvement, ranging from non-surgical interventions with intensive lubrication to permanent surgical punctal occlusion. While frequent lubrication is essential, the intense regime is often too burdensome and difficult to maintain at the required frequency. Punctal plugs are an invaluable alternative approach, but also have limitations, especially in conscious children, in whom inserting and re-inserting punctum plugs in clinic can be challenging. If a patient has permanent and severe dry eye disease and responded well to a trial of temporary punctal plugging, a permanent surgical solution should be considered next. Liu et al showed that a more successful, yet simple technique to achieve permanent occlusion is to combine de-epithelialising the punctum and ampulla with the immediate firm apposition of the de-epithelialised surface using a self-absorbable suture - with a success rate of 92% in a prospective study. This article demonstrates this technique step-by-step in an 8-year-old child with severe chronic dry eye disease following proton beam therapy for orbital rhabdomyosarcoma. She underwent this procedure with excellent results.

RESUMEN
Dry eye disease (DED) is a multifactorial disease affecting 5% to 50% in different populations. The most severe cases of DED are often caused by aqueous deficient dry eye disease (ADDE) due to lacrimal gland (LG) hypofunction. Many patients with severe ADDE do not experience adequate symptom relief from topical treatment, severely reducing their quality of life. The focus of this review is to describe the surgical interventions presently being used or investigated when topical treatment with eye drops is insufficient. The conventional surgical approach is to proceed to punctal occlusion or partial or total tarsorrhaphy. However, novel surgical procedures have been reported to have higher efficacy and patient satisfaction than conventional treatments. These procedures include amniotic membrane transplantation, transposition or transplantation of the salivary glands, and cell-based injections into the LG, each with strengths and weaknesses. Further development of these treatment modalities might prove pivotal in treating dry eye patients in the future.

PURPOSE: To evaluate the prevalence of dry eye symptoms after endoscopic dacryocystorhinostomy (EDCR) for patients with primary acquired nasolacrimal duct obstruction (PANDO) combined with dry eye syndrome. METHODS: The patients diagnosed with PANDO combined with dry eye syndrome who underwent EDCR were divided into two groups according to the questionnaire about dry eye symptoms after surgery. The medical records were retrospectively analyzed. Before and after surgery, we compared the tear meniscus height, tear breakup time, and the presence of corneal punctuate epithelial erosion. The level of dry eyes of patients after surgery was assessed by using the Korean guidelines for the diagnosis of dry eye. RESULTS: At 6 months after EDCR, the proportion of patients with dry eye symptoms was 30% in a total of 80 patients. The duration of epiphora and tear breakup time after EDCR were higher in the group without dry eye symptoms and the proportion of eyes with corneal punctuate epithelial erosion after EDCR was higher in the group with dry eye symptoms. About 15% of total patients started treatment with a dry eye of level 2 or higher. CONCLUSIONS: About 15% of patients who underwent EDCR for PANDO combined with dry eye syndrome developed significant dry eye syndrome after surgery. The short onset of epiphora was associated with the development of the dry eye symptoms. Therefore, it is necessary to evaluate dry eye syndrome before surgery, and surgeons should be careful about this.

PURPOSE: To compare subjective and objective dry eye syndrome (DES) metrics preoperatively and postoperatively in patients undergoing bilateral upper eyelid blepharoplasty (ULB) using orbicularis-sparing versus orbicularis-excising techniques. METHODS: A double-blind, randomized clinical trial was conducted on patients without prior DES or other severe conditions who presented to our institution between 2017 and 2019 for routine functional ULB. Patients were randomized into two treatment arms: bilateral ULB using the orbicularis-sparing technique or bilateral ULB using the orbicularis-excising technique. One subjective and seven objective DES assessments were performed on all patients preoperatively and 1 month and 1 year after surgery. RESULTS: A total of 63 patients were recruited for the study. Standard Patient Evaluation of Eye Dryness (SPEED) scores decreased in both treatment groups at 1 month and 1 year postoperatively. This change did not significantly vary based on surgical technique. Objective DES assessments were not significantly changed at both postoperative time points for either group. There was a correlation between the severity of preoperative DES symptoms and the subjective improvement of DES symptoms postoperatively in both groups. CONCLUSIONS: ULB with an orbicularis-sparing or orbicularis-excising technique does not worsen subjective or objective DES metrics and so, surgeons may confidently use either surgical technique. These findings may impact postoperative expectations for surgeons and patients alike.

Corneal perforations in eyes with dry eye disease (DED) are difficult to manage due to the interplay of several factors such as the unstable tear film, surface inflammation, and the underlying systemic disease affecting the wound healing process, and the eventual outcome. A careful preoperative examination is required to identify the underlying pathology, and status of ocular surface and adnexa, rule out microbial keratitis, and order appropriate systemic workup in addition to assessing the perforation itself. Several surgical options are available, which include tissue adhesives, multilayered amniotic membrane grafting (AMT), tenon patch graft (TPG), corneal patch graft (CPG), and penetrating keratoplasty (PK). The choice of procedure depends upon the size, location, and configuration of the perforation. In eyes with smaller perforations, tissue adhesives are effective treatment modalities, whereas AMT, TPG, and CPG are viable options in moderate-sized perforations. AMT and TPG are also preferable in cases where the placement of a bandage contact lens may be a challenge. Large perforations require a PK, with additional procedures such as tarsorrhaphy to protect the eyes from the associated epithelial healing issues. Conjunctival flaps are considered in eyes with poor visual potential. The management of the acute condition is carried out in conjunction with measures to improve the tear volume bearing in mind the chances of delayed epithelialization and re-perforation in these cases. Administration of topical and systemic immunosuppression, when indicated, helps improve the outcome. This review aims to facilitate clinicians in instituting a synchronized multifaceted therapy for the successful management of corneal perforations in the setting of DED.

Purpose: Dry eye disease (DED) might be caused by multiple ocular surgical interventions. The aim of the study was to estimate the extent of DED in patients undergoing core vitrectomy for vitreoretinal interface disorders. Methods: In this prospective observational study, we included patients with 12 months of follow-up after vitrectomy. The following data were collected as controls: age, sex, best-corrected visual acuity before and after surgery, and phakic status. In OSA (ocular surface analysis), the following parameters were evaluated: NIBUT (non-invasive tear break-up time), sltDear (thickness of the lipid layer), Meibomian gland (MGD) loss, and the height of tear meniscus. Shapiro-Wilk test, Wilcoxon rank-sum test, and Mann-Whitney U tests were used for statistical analysis. Results: We evaluated 48 eyes of 24 patients (10 men, 14 women; 64.63 ± 14.10 years) 1 year after vitrectomy. From the analyzed ocular surface parameters, NIBUT was significantly lower in operated versus non-operated eyes (P = 0.048). The higher the level of difference in MGD loss between both eyes, the higher the level of difference in NIBUT between both eyes (rs = 0.47, P = 0.032). Conclusion: NIBUT levels were still decreased 12 months after vitrectomy. Patients with more pronounced MGD loss or decreased NIBUT levels in the fellow eye were more likely to experience such disorders. The tear meniscus height was lower in patients undergoing surgery for retinal detachment than in those with vitreoretinal disorders. This might allow the suggestion to include artificial tears in pre- and post-operative care in vitrectomized eyes.

Purpose: To evaluate the effect of deep thermal punctal cautery in eyes with post-conjunctivitis cicatrization. Methods: This retrospective study consisted of patients who underwent deep thermal punctal cautery for post-conjunctivitis dry eye (PCDE). The diagnosis was based on a history suggestive of viral conjunctivitis in past followed by the onset of present clinical features of aqueous deficiency dry eye (ATD). All patients underwent a rheumatological evaluation to rule out underlying systemic collagen vascular disease as a cause for dry eye. The extent of cicatricial changes was noted. Best-corrected visual acuity (BCVA), Schirmer's test, and fluorescein staining score (FSS; total score of 9) were analyzed pre- and post-cautery. Results: Out of 65 patients (117 eyes), 42 were males. The mean age at presentation was 25.769 ± 12.03 years. Thirteen patients presented with unilateral dry eye. Pre-cautery BCVA (logarithm of the minimum angle of resolution [logMAR]) and Schirmer's test (mm) improved from 0.5251 ± 0.662 to 0.372 ± 0.595 (P value = 0.000, 95% confidence interval [CI]: 0.09-0.22), and 1.952 ± 2.763 to 4.929 ± 4.338 (P value = 0.000, 95% CI: -3.79--2.17); post-cautery, respectively. The pre-cautery FSS of 5.9 ± 2.82 reduced to 1.58 ± 2.38 (P value = 0.000, 95% CI: 3.46-5.17) post-cautery. The mean follow-up was 11.22 ± 13.32 months. No progression in cicatricial changes was noted in any eye during the follow-up. Re-canalization rate was 10.64%, and repeat cautery was performed with successful closure of puncta. Conclusion: Symptoms and clinical signs of ATD in PCDE patients improve with punctal cautery.

Bilateral corneal blindness with severe dry eye disease (DED), total limbal stem cell deficiency with underlying corneal stromal scarring and vascularization, combined with adnexal complications secondary to chronic cicatrizing conjunctivitis is a highly complex situation to treat. In such eyes, procedures such as penetrating keratoplasty alone or combined with limbal stem cell transplantation are doomed to fail. In these eyes, keratoprosthesis (Kpro) or an artificial cornea is the most viable option, eliminating corneal blindness even in eyes with autoimmune disorders such as Stevens-Johnson syndrome, ocular mucous membrane pemphigoid, Sjogren's syndrome, and nonautoimmune disorders such as chemical/thermal ocular burns, all of which are complex pathologies. Performing a Kpro in these eyes also eliminates the need for systemic immunosuppression and may provide relatively early visual recovery. In such eyes, the donor cornea around the central cylinder of the Kpro needs to be covered with a second layer of protection to avoid desiccation and progressive stromal melt of the underlying cornea, which is a common complication in eyes with severe DED. In this review, we will focus on Kpro designs that have been developed to survive in eyes with the hostile environment of severe DED. Their outcomes in such eyes will be discussed.

BACKGROUND: To introduce and evaluate the efficacy of a simple punctal occlusion technique for dry eye patients. METHODS: Medical records of 79 eyes from 40 patients refractory to common dry eye conservative treatment who underwent multiple high-frequency radio-wave electro-punctal occlusion were retrospectively reviewed. Pre- and post-procedural ocular surface indices (Schirmer test, tear break-up time (TBUT), and corneal staining grade (Oxford scheme)) and subjective symptom scores (including frequency of artificial tear use, interval between procedures, and total repeat time) were analyzed. RESULTS: Average Schirmer test result was significantly (P < 0.05) improved from 4.10 ± 1.39 mm to 8.14 ± 3.13 mm at 6 weeks after the procedure (n = 79). A total of 32 eyes from 16 patients underwent repeated procedure with a mean interval of 8.00 ± 4.86 months, while 24 patients had a single procedure. Twenty-five of 30 patients showed improvement for subjective symptom scores. No complications related to the procedure were observed. CONCLUSIONS: A simple, less-invasive punctal occlusion technique using a fine-needle tip with high-frequency radio-wave could significantly relieve subjective symptoms and improve ocular surface indices of patients with aqueous deficient dry eye without causing a major complication. This procedure may play a considerable role in treating dry eye refractory to common practices.

PURPOSE: To evaluate dry eye and anterior segment inflammation after small incision lenticule extraction (SMILE) and femtosecond laser-assisted in situ keratomileusis (FS-LASIK), and investigate their association. METHODS: This prospective and observational study included 96 eyes from 48 myopic patients. The evaluation was performed at baseline, postoperative day 1, week 1, month 1 and month 3. Outcome measures included anterior chamber flare, bulbar redness (BR), limbal redness (LR), ocular surface disease index (OSDI), tear meniscus height (TMH), the first and average noninvasive breakup time (NIBUT-1, NIBUT-a), fluorescein breakup time (FBUT), corneal fluorescein staining (CFS), and Schirmer I. Generalized estimating equations (GEEs) were applied to explore the correlation between flare and ocular surface parameters. RESULTS: Flare increased significantly in both groups at day 1 and week 1 and then returned to baseline at month 1. In both groups, BR decreased on day 1 and then gradually increased towards the baseline. In FS-LASIK, LR was lower than baseline at day 1 and month 3. An increase in OSDI was found in the SMILE group on day 1, and in the FS-LASIK group at day 1 to month 1. NIBUT-1 and NIBUT-a decreased significantly on day 1 in both groups. At month 3, NIBUT-a did not return to baseline in FS-LASIK. CFS increased significantly at week 1 in both groups. All parameters were comparable between SMILE and FS-LASIK except for OSDI and NIBUT-a. Time and spherical equivalent showed a correlation with flare. CONCLUSIONS: Both SMILE and FS-LASIK induced elevated anterior chamber flare and dry eye. However, flare might not be considered a factor determining perioperative dry eye.Key MessagesDry eye disease is common after corneal refractive surgery. Signs and symptoms of dry eye disease persist longer after FS-LASIK compared with SMILE.Both FS-LASIK and SMILE transiently disrupted blood-aqueous barrier integrity, leading to anterior segment inflammation.Anterior chamber flare might not be considered a factor explaining perioperative dry eye, other biomarkers remain for future exploration.

With the advancement in the study of keratoconjunctivitis sicca and the scope of its treatment, punctal plugs are being widely used for the therapeutic management of dry eye disease. With the emergence of 3D printing in medicine, 3D printing of punctal plugs that have an inbuilt drug delivery system and also that can be personalized from patient to patient according to their punctum size can be a great therapeutic option. Another benefit of the device is that its printing takes a short period of time and is cost-effective. This study aimed at making an open source design and 3D printing an efficient model of a punctal plug with an inbuilt drug delivery system that can be eventually used for the treatment of various ocular diseases that require frequent drug instillation or blockage of the nasolacrimal pathway. The 3D design for the punctal plug was made using the open source application, FreeCAD, and slicing was done using the application ChituBox. After that, the plugs were printed using the LCD printer Crealty LD-002R. The material used was resin that was compatible with the Crealty LD-002R. Punctal plugs with satisfactory results were printed using the LCD printer. The punctal plugs showed suitable structure and were also easily reproduced in the 3D printer without any complications or setbacks.

PURPOSE: To determine the effect of unilateral primary acquired nasolacrimal obstruction (PANDO) on ocular surface parameters in PANDOeyes and fellow eyes and changes in these parameters after dacryocystorhinostomy. METHODS: Tear osmolarity, tear break-up time (TBUT), Schirmer's test, Meibomian gland score, and Lissamine Green staining of PANDO eyes and fellow eyes were measured preoperatively and postoperatively at Day 15, 1 month, and 3 months. Lacrimal irrigation and epiphora symptomatology were evaluated at all follow-up visits, and patients who did not meet surgical success criteria were excluded from the study. RESULTS: Twenty-nine patients who underwent successful dacryocystorhinostomy surgery were included in the study. Preoperative and postoperative Day 15 Schirmer (p = .019, p = .001) and TBUT (p = .039, p = .043) were significantly lower in the fellow eye compared to PANDO eyes. The differences observed between PANDO eyes and fellow eyes in all other parameters were not significant (p > .05). Preoperatively PANDO eye parameters were normal, whereas TBUT (7.59 ± 5.39 s) and tear osmolarity (308.59 ± 17.32 mOsm/L) values of the fellow eye may be indicative of tear film instability. TBUT and tear osmolarity of the fellow eye showed significant improvement 3 months postoperatively compared to preoperative values (p = .010; p = .027 respectively). CONCLUSION: Schirmer and TBUT values of the fellow eye were significantly lower than PANDO eyes preoperatively, one month after surgery there was no significant difference. TBUT and tear osmolarity of the fellow eyes may be indicative of tear instability preoperatively with improvement 3 months after dacryocystorhinostomy.

PURPOSE: No specific interventions have been reported for the treatment of severe neurodeprivative dry eye disease owing to facial nerve palsy. We describe herein the feasibility of a novel surgical procedure to reinnervate the lacrimal gland and report the preliminary outcomes of the first series of patients who were treated accordingly. METHODS: Prospective interventional case series including consecutive patients affected by facial palsy with absolute deficiency of tear secretion who underwent lacrimal gland neurotization. A sural nerve vertical cross-face graft was used to connect the lacrimal gland with the parasympathetic branch of the lingual nerve directed to the contralateral submandibular gland. RESULTS: Lacrimal neurotization was performed uneventfully in 10 patients (4 M, 6 F; mean age 47.1 ± 17.1 years). In all cases, the procedure was combined with facial reanimation, while corneal neurotization was performed in 4 cases. One year postoperatively, mean values of a Schirmer test increased significantly compared with baseline values (7.56 ± 7.84 vs. 0 ± 0 mm/5 min; P = 0.02), while the mean daily number of instillation of tear substitutes decreased significantly (21.8 ± 4.5 vs. 7.1 ± 2.2; P = 0.009). Overall, all patients were satisfied with surgery (very satisfied: n = 7 and satisfied: n = 2). No major postoperative complications occurred. CONCLUSIONS: Vertical cross-face using a sural nerve graft to connect the lacrimal gland with the contralateral submandibular gland is a novel technique for treating patients with facial nerve palsy and severe neurodeprivative dry eye disease. This surgery both performed alone and combined with corneal neurotization is able to improve tear secretion and decrease the need for frequent instillations of tear substitutes.

The transplantation of salivary glands to the eye serves as a substitute for restoring tear volume in patients with severe dry eye disease. The lacrimal gland and salivary glands share similar acinar-ductal organization with some differences in the nature of secretions. This review summarizes the comparative anatomy of salivary and lacrimal glands, various salivary gland transplantation techniques, their indications, outcomes and complications along with future perspectives. Autologous microvascular submandibular gland transplantation (SMGT) into the temporal fossa with duct placement into the conjunctival fornix improves tear volume considerably but provides a hyposmolar tear film, which can induce corneal edema (in 3.5-40% of eyes). The transplanted submandibular graft improves tear volume and stability but visual acuity and conjunctival inflammation remain unchanged. The transplanted submandibular gland maintains stable function in the long-term and can have hypersecretion in 24-60% secondary to persistent autonomic innervation. Partial SMGT, gland reduction surgery, topical atropine gel or Botulinum Toxin A injection are options for treatment of postoperative epiphora. Minor salivary gland transplantation (MSGT) into the upper and/or lower conjunctival fornix results in an average improvement of 2-4 mm in Schirmer values compared to 16 to > 30 mm observed in eyes after SMGT. Reflex epiphora is rarely a problem in MSGT. Both MSGT or SMGT can improve the ocular surface and quality of life of patients with severe, debilitating dry eye disease. However, postoperative visual acuity and outcomes of corneal transplantation are still inconsistent. More studies and additional technical improvements are needed to further improve the results of these procedures.
