“…This happens because of the equatorial age-related growth of the lens which makes the suspensory ligament slackens and the lens moves anteriorly [3]. Phacoemulsification for cataract or even lens extraction with IOL implantation in eyes with narrow angle can reduce the intraocular pressure (IOP), open the iridocorneal angles and deepen the anterior chamber [3][4][5][6][7][8][9][10].…”

. Purpose: We set out to quantify changes in the anterior chamber volume (ACV), anterior chamber depth (ACD) and anterior chamber angle (ACA) measurements obtained by the Pentacam rotating Scheimpflug camera following uneventful phacoemulsification surgery in normotensive eyes with open iridocorneal angles. Methods: We enrolled 44 eyes of 44 consecutive patients undergoing cataract extraction in this prospective study. Patients with a history of glaucoma, angle‐closure glaucoma or any other concurrent ocular disease were excluded. A detailed eye examination including intraocular pressure (IOP) measurement was performed and ACV, ACD and inferior, superior, temporal and nasal ACA measurements were obtained in each patient eye using the Pentacam Comprehensive Eye Scanner (Pentacam CES) before and 3 months after phacoemulsification and intraocular lens (IOL) implantation with temporal clear corneal incision. Data were compared using paired t‐test and one‐way anova. Results: Mean preoperative ACV, ACD, ACA and IOP measurements were 164.7 ± 49.8 mm3, 3.0 ± 0.8 mm, 35.7 ± 10.2 ° and 15.8 ± 3.7 mmHg, respectively. Three months postoperatively, mean ACV, ACD, ACA and IOP measurements were 200.9 ± 33.3 mm3, 3.9 ± 0.9 mm, 41.5 ± 6.5 ° and 13.2 ± 3.9 mmHg, respectively. Postoperative mean ACV, ACD and ACA values in all four quadrants were significantly increased (p < 0.0001, p < 0.0001, p < 0.0001, respectively), whereas IOP was significantly reduced (p < 0.0001). Conclusions: The Pentacam CES allowed very easy, fast, automatic and non‐contact quantification of the anterior chamber parameters pre‐ and postoperatively in all patient eyes. Measurements obtained confirm that in normotensive eyes with open iridocorneal angles, the ACV and ACD increase and the ACA widens in all quadrants 3 months after uneventful phacoemulsification and IOL implantation. These changes are accompanied by a significant fall in IOP in the short term.

Aumento (1,2,(4)(5)(6) ou diminuição (3) do ACD após a facectomia já foram previamente demonstrados, assim como uma redução da PIO (4)(5)(6)(7) .…”

RESUMOObjetivo: Avaliar comparativamente a pressão intraocular (PIO) antes e após 1 dia, 3 dias, 1 semana, 1 mês, 3 meses, 6 meses e 1 ano, em olhos normais submetidos à facoemulsificação. Métodos: Análise retrospectiva da pressão intraocular (medida pelo tonômetro de aplanação de Goldmann) de 221 olhos normais de 133 pacientes submetidos à facoemulsificação sem intercorrências. A PIO foi avaliada antes e após a facoemulsificação (1dia, 3 dias, 1 semana, 1 mês, 3 meses, 6 meses e 1 ano), e os valores encontrados nestes períodos foram submetidos a uma análise comparativa. Resultados: A PIO média foi de 16,06±2,69 mmHg no pré-operatório; 18,76±5,96 mmHg após 1 dia; 14,82±4,08 mmHg após 3 dias; 14,03±3,06 mmHg após 1 semana; 13,88±3,26 mmHg após 1 mês; 12,74±2,45 mmHg após 3 meses; 12,74±2,01 mmHg após 6 meses; e 13,24±2,77 mmHg após 1 ano. A PIO aumentou 18,9% após 1 dia; diminuiu 6,9% após 3 dias; 12,3% após 1 semana; 12,5% após 1 mês; 19,3% após 3 meses; 20,1% após 6 meses; e 19,9% após 1 ano. Conclusão: A cirurgia de facoemulsificação sem intercorrências leva a uma redução significativa da PIO em olhos normais. A diminuição da PIO é mais acentuada naqueles pacientes que apresentam PIO mais alta no pré-operatório.

Anterior chamber depth, iridocorneal angle width, and intraocular pressure changes after uneventful phacoemulsification in eyes without glaucoma and with open iridocorneal angles

Abstract: In nonglaucomatous eyes with an open ICA preoperatively, uneventful phacoemulsification reduced IOP, increased ACD, and widened the ICA. The changes were statistically significant over 6 months.
