Objectives: To investigate the clinical characteristics of cataract patients with small pupils and to evaluate the result of cataract surgery on the eye have small pupils by phacotechnique. Subjects and methods: Descriptive study, prospective, uncontrolled interventions. Sample selection. The sample size of 70 patients with 70 eyes of cataracts with small pupils was treated by phaco technique and intraocular lens implant within posterior chamber. Follow up to 3 months. Results: 70 eyes, the percentage of men and women was not different from 54.2% (38 male) compared to 45.8% (32 female). The mean age was 80 ± 8.74, from 58 to 99 years. The disease was mainly found in the age group over 70 years old with over 80% (51.5%). Visual acuity before surgery was very poor under 3m CF (count finger) for 68.6% (48/70). Visual acuity over 1/10 was only a small amount with 2.8% (2 eyes). Pseudoexfoliation was the most common reason complications of mydriasis with 32/70 eyes (45.7%) and 22/70 eyes (31.4%) for age. The preoperative pupilarysizewas mostly small with 63/70 eyes (90.0%), non-dilated pupils (7/70 eyes) (10.0%). Average pupil size was 3.34 mm (2 - 4mm). Iris condition: iris atrophy 20/10 eyes (28.6%), iris synechiae 11/10 (15.7%), irregular iris muscle with 51, 4% and good iris muscle accounted for 48.6%. Grade of cataract: Grade III: 31/70 eyes (44.3%), Grade IV: 32/70 eyes (45.7%), Grade II: 5/70 eyes (7.1%) and V:2/70 eyes (2.9%). Pupil expander technique: OVD injection with 42/70 eyes (60%), using iris hook with 23/70 eyes (32.9%). Pupillary size before and after intervention has changed from 3.7mm to 4.48mm. Conclusions: Iris expander techniques have been shown to have good dilated pupils: 60.0% OVD injection, iris hook was 32.9%, other methods 7.1% One-week visibility of good visual acuity was higher than that of postoperative one day (12.2%) and increased at 1 month and 3 months (20.0%). Very good visual acuity was not available and low vision group was 1.4% after 3 months. Key words: cataract surgery; phacoemusification, small pupil

Objective: To investigate the clinical outcomes of three surgical approaches for ectopia lentis in Marfan syndrome (MS) patients who had undergone crystalline lens removal with posterior chamber intraocular lens (IOL) implantation techniques comprising the intrascleral fixation of IOL, sutured scleral fixation of IOL, and IOL implantation with the use of a Cionni capsular tension ring (CTR). Methods: This is a retrospective comparative study, including 35 eyes of 21 patients who underwent the intrascleral fixation of IOL (group 1), scleral IOL fixation with the Z-suture (group 2), and IOL implantation with the use of a Cionni CTR (group 3) following crystalline lens removal. The surgical indications were as follows: no improvement in visual function after eyeglasses or contact lens application due to excessive irregular astigmatism and advanced crystalline lens decentration in which the edge of the crystalline lens came up to the optical axis, or dislocation of the crystalline lens resulting in aphakia and secondary glaucoma due to lens dislocation. The surgical outcomes and complications due to surgery were compared between the groups. Results: The mean age of the patients in the study was 12.3 ± 8.7 years (5–32 years). There were 10 eyes in group 1, 13 eyes in group 2, and 12 eyes in group 3. Visual acuity improved significantly in each group after surgery. Ocular residual astigmatism did not differ significantly between the groups ( p = 0.51). Conclusion: There were no significant differences between the three surgical approaches in the current study in terms of the postoperative results and complications.

Intraocular foreign bodies (IOFB) present differently depending on the type of material (wood, glass, metal) for the IOFB, extent of the injury, and location of the injury. IOFB and the injury can cause a perforation or penetration of the globe which can require more extensive treatment including surgery. Proper evaluation of the IOFB and injury can help to determine extent of the injury, the prognosis of the vision, and health of the eye before and after treatment but may be difficult for the physician depending on the view of the posterior chamber being compromised by media or simply by patient sensitivity. The extent of the injury may also prevent proper evaluation due to swelling, lacerations on the lids, or pain. Proper ophthalmic sonography can provide a quick evaluation of the globe for any IOFB in both the outpatient setting as well as emergency department setting. Evaluation via sonography may allow the physician to accurately diagnose and properly treat the patient to help restore and prevent further loss of vision.

A patient presented with complaints of a sudden decrease in vision, ocular redness, and pain in the right eye. The patient had a history of clear lens extraction with intraocular lens (IOL) implantation for myopia 2 years previously. He had been prescribed topical steroids for episodes of inflammation that occurred repeatedly every 1–2 months. With a presumptive diagnosis of chronic endophthalmitis, a 23-G transconjunctival sutureless pars plana vitrectomy (PPV) with delivery of intravitreal antibiotics was performed the next day. Culture sensitivity testing of the vitreous sample indicated <i>Pseudomonas stutzeri</i> that was sensitive to ceftazidime and gentamicin. Two weeks later, the patient presented with sudden loss of vision and all the signs of recurrent endophthalmitis. 23-G transconjunctival sutureless PPV was performed along with removal of the posterior chamber IOL through a corneal incision. Complete resolution was only achieved after removal of the IOL, resulting in excellent visual recovery. Due to its chronic and fulminating nature, <i>P. stutzeri</i> can induce endophthalmitis and should be considered in the differential diagnosis. Aseptic measures are the best prevention.
