PURPOSE: To evaluate corneal viscoelastic and intraocular pressure (IOP) changes measured by an ocular response analyzer (ORA) after phacoemulsification and intraocular lens (IOL) implantation.SETTING: Yeditepe University Department of Ophthalmology, Istanbul, Turkey.METHODS: Fifty-one eyes scheduled for cataract surgery were included in the study. Corneal hysteresis (CH), corneal resistance factor (CRF), corneal-compensated intraocular pressure (IOPcc), and Goldmann-correlated IOP (IOPg) were measured by ORA preoperatively and 1 week and 1 and 3 months postoperatively. Central corneal thickness (CCT) was measured using the ORA's integrated handheld ultrasonic pachymeter. RESULTS:The mean preoperative CCT (537 mm G 46 [SD]) did not change significantly by the end of 1 month postoperatively. The mean preoperative IOPcc (17.2 G 3.0 mm Hg) decreased significantly by 3 months postoperatively (15.2 G 3.7 mm Hg) (P Z .018). The mean CH decreased from 10.36 G 1.48 mm Hg preoperatively to 9.64 G 1.26 mm Hg at 1 week (P Z .028); it increased to preoperative values at the end of 1 month (10.20 G 1.70) and 3 months (10.74 G 1.54) (P>.05). The mean CRF decreased from 10.94 G 2.54 mm Hg preoperatively to 9.99 G 1.77 at 1 week (P Z .026); it increased to preoperative values at 1 month (10.26 G 1.59) and 3 months (10.35 G 1.46) (P>.05). CONCLUSIONS: Although CH and the CRF decreased in the early postoperative period, the parameters increased and reached preoperative values by 3 months postoperatively, showing that corneal biomechanical properties are influenced by phacoemulsification and IOL implantation.

Deepening of the anterior chamber and widening of the nasal and temporal angles after cataract extraction was shown on AS-OCT.

Topical and systemic FFP treatment and conjunctival membrane excision may help rapid rehabilitation and prevent recurrence in cases with ligneous conjunctivitis.

ABSTRACT.Purpose: To determine the haemodynamics of the ciliary choroidal system in diabetics with or without systemic hypertension. Methods: 90 eyes of 45 diabetic patients were included into the study. Patients were divided into two groups based on the presence of systemic hypertension. The pulsatile component of the total ocular blood flow in diabetics with or without hypertension was analyzed using ocular blood flow tonograph (OBF Labs, UK). The control group was comprised of 40 age-matched eyes of 20 volunteers with no ocular or systemic disease. Results were compared with the control group. Results: Pulse amplitude (PA), pulse volume (PV) and pulsatile ocular blood flow (POBF) were significantly lower (p∞0.05) in diabetics without systemic hypertension than the controls. In diabetics with hypertension, although the systolic and diastolic blood pressures were significantly higher than the control group, there was not any statistically significant difference (pϾ0.05) between PA, PV and POBF results. Conclusion: POBF was found to be lower in diabetics without hypertension compared to the controls. Such a presence of systemic hypertension may increase the choroidal blood flow in diabetics.

The qualitative and quantitative evaluation of the corneal flap created by a femtosecond laser using AS-OCT before lifting the flap confirms that the femtosecond laser is a practical intraoperative approach that offers a safer surgery.
