    Comparison of Transcanalicular Diode Laser Dacryocystorhinostomy and External Dacryocystorhinostomy in Patients with Primary Acquired Nasolacrimal Duct Obstruction
    (Wiley-Blackwell, 2014) Comez, Arzu Taskiran; Karadag, Onur; Arikan, Sedat; Gencer, Baran; Kara, Selcuk
    Background and Objective: To compare the success, complication, and patient discomfort rates of transcanalicular diode laser dacryocystorhinostomy (TCDL-DCR) and external dacryocystorhinostomy (EX-DCR) surgeries performed in patients with primary acquired nasolacrimal duct obstruction. Materials and Methods: Eighty consecutive patients were included in the study, and groups were assigned according to DCR technique. Thirty-four (42.5%) patients received TCDL-DCR (Group A) and 46 (57.5%) patients (Group B) received EX-DCR with temporary silicone stent intubation. The success of surgery was determined by the relief of epiphora, patient satisfaction, endoscopic evaluation of ostium patency, and lacrimal system syringing. Pearson Chi-Square test, Fisher's Exact test, and Student's t-test were used for statistical analyses. Results: Group A included 22 females and 12 males with a mean age of 49.1 +/- 15.1 years, Group B included 35 females and 11 males with a mean age of 50.8 +/- 11.7 years. There was no difference between groups in terms of age and gender (P=0.905 and P=0.167, respectively). The duration of the operation was 22.2 +/- 4.8 minutes for Group A, while it was 56.3 +/- 15.7 minutes for group B (P=0.0001). In two patients in Group A, injury in the medial turbinate was recorded, and in Group B, 14 patients experienced mild to severe perioperative bleeding. The perioperative complication rate was significantly different between the groups (P=0.004). Success in relieving symptoms was 79.4% for Group A and 89.1% for Group B. The difference in the success rates was not statistically significant (P=0.229). Conclusions: Although EX-DCR success rate was higher than that achieved with TCDL-DCR, the latter, with its shorter duration of surgery, lower perioperative complication rate, and a similar success rate, may be a good and acceptable surgical alternative in treatment of primary acquired nasolacrimal duct obstruction.

    Simultaneous Bilateral Phacoemulsification and Intraocular Lens Implantation
    (Turkish Ophthalmological Soc, 2013) Akcay, Levent; Comez, Arzu Taskiran; Ozgur, OZlen Rodop; Karadag, Onur; Kaplan, Aysin Tuba; Dogan, Omer Kamil
    Purpose: To assess the visual outcomes, benefits, and drawbacks of simultaneous same-day phacoemulsification and intraocular lens (IOL) implantation in patients having bilateral cataracts. Material and. Method: The medical records of 346 patients (692 eyes) with bilateral cataracts who have undergone simultaneous bilateral cataract extraction (SBCE) with phacoemulsification and IOL implantation performed by a single surgeon (LA), were reviewed retrospectively. Outcome measures were intraoperative and postoperative complications, best-corrected postoperative visual acuity (BCVA), refractive errors, and patient satisfaction. Results: BCVA increased in 633 (91.5%) eyes, decreased in 12 (1.73%) eyes, and remained the same in 47 (6.8%) eyes. The incidence of intraoperative complications was 7.2% (n=50). These complications included posterior capsule rupture with vitreous loss in 20 eyes (2.8%) and without vitreous loss in 17 eyes (2.4%), zonular dehiscence in 9 eyes (1.3%), IOL haptic fracture in 2 eyes (0.28%), iridodialysis in 1 eye (0.14%), and nuclear drop in 1 eye (0.14%). Late postoperative complications occurred in 31 eyes (4.5%). Discussion: With a careful preoperative evaluation performed by an experienced surgeon under strict surgical protocol, simultaneous bilateral phacoemulsification and IOL implantation may be a beneficial procedure surgical success rate.
