“…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].…”

“…Other studies had already demonstrated the improvement in anterior chamber parameters after cataract surgery [22][23][24][25][26] but this, to our knowledge, has the longest follow-up, demonstrating the stability of these changes, as well as their effect in IOP control.…”

Phacoemulsification versus peripheral iridotomy in the management of chronic primary angle closure: long-term follow-up

Primary angle closure occurs as a result of crowded anterior segment anatomy, causing appositional contact between the peripheral iris and trabecular meshwork, thereby obstructing aqueous outflow. Several studies highlight the role of the crystalline lens in its pathogenesis. The objective of this work is to compare the long-term efficacy of phacoemulsification versus laser peripheral iridotomy (LPI) in the management of chronic primary angle closure (CPAC). Prospective case-control study with 30 eyes of 30 patients randomly divided in two groups: 15 eyes in the LPI group and 15 eyes in the IOL group. Patients in the LPI group underwent LPI using argon and Nd:YAG laser. Patients in the IOL group underwent phacoemulsification with posterior chamber intraocular lens (IOL) implantation. Examinations before and after the procedure included gonioscopy, Goldmann applanation tonometry, and anterior chamber evaluation using the Pentacam rotating Scheimpflug camera. The mean follow-up time was 31.13 ± 4.97 months. There was a statistically significant reduction in the intraocular pressure (IOP) and number of anti-glaucoma medications (p \ 0.01) only in the IOL group. Anterior chamber depth, angle, and volume were all higher in the IOL group (p \ 0.01) at the end of the follow-up period. Phacoemulsification with posterior chamber IOL implantation results in a higher anterior chamber depth, angle, and volume, when compared to LPI. Consequently, phacoemulsification has greater efficacy in lowering IOP and preventing its long-term increase in patients with CPAC and cataract.

“…Other antiglaucoma medications were discontinued and restarted according to IOP response. To evaluate the medical antiglaucomatous treatment, we used a scoring system as used by Kubota et al 6 In this one point was assigned for each antiglaucomatous medication and two points for oral acetazolamide. At each postoperative follow-up, complete ocular examination including gonioscopy was done in all the patients.…”

Purpose To evaluate the safety and intraocular pressure (IOP) lowering effect of combined phacoemulsification and viscogonioplasty (Phaco-VGP) in managing primary acute closed-angle glaucoma (ACAG) unresponsive to conventional therapy (patent PI). Patient and Methods In all, 15 consecutive eyes of patients with refractory ACAG and greater than 2701 peripheral anterior synechiae (PAS) underwent VGP. The technique of VGP involved routine phacoemulsification with intraocular lens implantation (Phaco/IOL) under topical anaesthetic. Following IOL implantation a heavy viscoelastic was used to deepen the anterior chamber and then injected near the angle for 3601 (without touching the trabecular meshwork) to break the PAS. No surgical instrument was used to physically break the PAS. Upon completion of VGP, automated irrigation with balanced salt solution to remove the viscoelastic was performed. Results Mean IOP reduced from 52.1 to 14.1 mmHg by Phaco-VGP at 6-months review. 14/15 patients were free of glaucoma medications at 6-month review. All angles showed exposure of the trabecular meshwork over 3601 postoperatively without evidence of residual synechiae. No untoward complications were observed in any patient. Conclusion VGP may have a role in controlling IOP effectively and safely in patients with refractory ACAG. It produces a large drop in the IOP and opening of the angle. It is a relatively simple technique to learn and we would recommend its use in the eyes of all patients who have had ACAG and are undergoing cataract extraction.
