Objectives
To investigate the effect of absorbable suture on surgically-induced corneal astigmatism in 3.0-mm sclera tunnel cataract surgeries.
Methods
Medical records of patients who underwent phacoemulsification cataract surgery using a 3.0-mm sclera tunnel incision made by a single surgeon were reviewed. Uncorrected distant visual acuity, corneal astigmatism and surgically-induced astigmatism were measured in 56 patients' eyes that underwent sclera tunnel cataract surgery with absorbable sutures (sutured group) and in 23 patients' eyes without sutures (unsutured group). Uncorrected visual acuity, intraocular pressure, slit lamp examination, and automated keratometry were evaluated preoperatively and at 3 days, 2 weeks, 4 weeks, and 8 weeks after cataract operation.
Results
There were no significant differences in preoperative average uncorrected distant visual acuity of the two groups (sutured group: 0.79 ± 0.64, unsutured group: 0.68 ± 0.72, P = 0.145). Corneal astigmatism measured using keratometry in the sutured and unsutured group at postoperative day 3 were 2.27 ± 2.12 D versus 0.83 ± 0.55 D at (P < 0.001), a difference which had disappeared after 4 weeks. Surgically induced astigmatism using the Holladay and Vector methods showed similar outcomes, suggesting that the sutured group exhibited higher astigmatism compared with the unsutured group until 2 weeks post-surgery.
Conclusions
TPatients undergoing scleral tunnel cataract surgery with absorbable sutures have greater surgically induced astigmatism, especially in the early postoperative period, compared with those without sutures. However, this surgically induced astigmatism due to absorbable sutures in scleral tunnel cataract surgery is temporary and disappears at 4 weeks post-surgery.

Objectives
To identify the relationship between surgical success rate and preoperative nasal mucosal thickness around the lacrimal sac fossa, as measured using computed tomography.
Methods
We reviewed 33 eyes from 27 patients who underwent endoscopic dacryocystorhinostomy after diagnosis of primary nasolacrimal duct obstruction and who were followed-up with for at least six months between 2011 and 2014. We measured preoperative nasal mucosal thickness around the bony lacrimal sac fossa using computed tomography and analyzed patient measurements after classifying them into three groups: the successfully operated group, the failed operation group, and the non-operated group.
Results
Surgery failed in six of the 33 eyes because of a granuloma at the osteotomy site and synechial formation of the nasal mucosa. The failed-surgery group showed a clinically significantly greater decrease in nasal mucosal thickness at the rearward lacrimal sac fossa compared with the successful-surgery group. However, nasal mucosal thickness of fellow eyes (i.e., non-operated eyes) was not significantly different between the two groups, and the location of the uncinate process did not appear to influence mucosal thickness. In the failed group, posteriorly located mucosal thickness of operated eye fossa was thinner than that of the non-operated eyes, but not significantly so.
Conclusions
Our results from this quantitative anatomical study suggest that nasal mucosal thickness is a predictor of endoscopic dacryocystorhinostomy results.

Objectives
To assess the inadvertent intraocular retention of perfluorocarbon liquid (PFCL) after vitreoretinal surgery and their complications.
Methods
We retrospectively reviewed the medical records of 108 patients who underwent vitreoretinal surgeries using intraoperative PFCL (perfluoro-n-octane (C8F18), 0.69 centistoke at 25℃, PERFLUORN®, Alcon, USA) and the removal of PFCL through fluid-air exchange. The analysis was focused on the occurrence of intraocular retained PFCL, diagnoses, surgicalprocedures, and complications.
Results
Retinal detachment (51 cases, 47%) was the most common surgery which used PFCL intraoperatively. Other causes were vitreous hemorrhage (24 cases, 22%), posteriorly dislocated lens (22 cases, 21%), and trauma (11 cases, 10%). Intraocular PFCL was found in a total of 9 (8.3%) eyes. PFCL bubbles remained in anterior chamber and vitreous cavity were observed in 4 cases and subretinal retained PFCL was observed in 5 cases. Three of 5 cases of subretinal PFCL exhibited in subfoveal space. Among the three subfoveal cases, macular hole developed after PFCL removal in 1 case, epiretinal membrane in the area where had been PFCL bubble. However, we observed no complications in 1 case of subfoveal PFCL that was removed by surgery. PFCL in anterior chamber and vitreous cavity were in 4 cases.
Conclusions
The presence of subfoveal PFCL might affect visual and anatomic outcomes. However, subfoveal PFCL may induce visual complications, and therefore requires special attention.
