Aim. To study the changes of anatomic and topographic characteristics of the eye anterior segment after uncomplicated cataract phacoemulsification using corneal incision with intraocular soft lens implantation. Methods. The data of ultrasound biomicroscopy and noncontact tonometry of 58 eyes (56 patients, 32 females, 24 males aged 54 to 78 years) before and after cataract phacoemulsification were analyzed. Paitents with survived ocular trauma, refractive keratoplasty, glaucoma, uveitis, and surgical complications (incomplete capsulorrhexis, posterior capsule rupture, ciliary zonule disinsertion, corneal burn). Apart from the common examinations (visual acuity testing, tonometry, tonography, eye A- and B-ultrasonography, biomicroscopy), all patients underwent eye ultrasound biomicroscopy. Results. Anterior chamber depth increased from 2.73±0.10 to 4.17±0.06 mm (p ≤0.001). Trabecula-iris distance measured at 500 μm from the scleral spur, increased from 0.38±0.02 to 0.47±0.02 mm (p ≤0.001). Anterior chamber angle increased from 28.69±1.87 to 42.73±1.56 degrees (p ≤0.001), the angle between the iris and the sclera increased from 32.78±1.39 to 41.36±0.84 degrees (p ≤0.001), the angle between the sclera and ciliary processes increased from 39.48±1.29 to 45.30±1.16 degrees (p ≤0.001). Intraocular pressure according to the non-contact tonometry data decreased from 18.16±1.29 to 13.55±0.95 mm Hg (p ≤0.001). Conclusion. Anterior chamber depth, trabecula-iris distance, anterior chamber angle, the angle between sclera and iris and the angle between sclera and ciliary processes increased significantly after phacoemulsification with intraocular lens implantation. Intraocular pressure decreased significantly according to the non-contact tonometry data.

Purpose.To assess intraocular pressure (IOP), lens vaulting, and anterior chamber (AC) angle width, following V4C implantable Collamer lens (ICL) procedure for myopic refractive error.Methods.A prospective case series that enrolled 54 eyes of 27 patients that were evaluated before and after V4C phakic posterior chamber Collamer lens implantation for correction of myopic refractive error. Preoperative measurement of IOP was done using Goldmann applanation tonometer and anterior chamber angle width using both Van Herick slit lamp grading system and Scheimpflug tomography imaging (Oculus Pentacam). Follow-up of the aforementioned variables was at 1, 6, and 18 months postoperatively, together with ICL vault measurements.Results.The mean baseline IOP of11.69±2.15showed a statistically significant (P=0.002) increase after 1 month that remained unchanged at 6 and 18 months postoperatively, with mean value of16.07±4.12,16.07±4.10, and16.07±4.13, respectively. Pentacam AC angle width showed a statistically significant decrease at 1(P=0.025), 6(P=0.016), and 18(P=0.010)months postoperatively, with mean preoperative value of40.14±5.49that decreased to25.28±5.33,25.46±5.44, and25.49±5.38, at 1, 6, and 18 months, respectively. Mean ICL vault showed moderate correlation with Pentacam AC angle width at 1(r=-0.435)and 6(r=-0.424)months.Conclusion. V4C ICL implantation resulted in decrease in AC angle width and increase in IOP, within acceptable physiological values at all time points.

Can preoperative anterior chamber angle width predict magnitude of intraocular pressure change after cataract surgery?
