A Prospective Study

Background: The aim of the study is to investigate whether the circadian IOP rhythm can be influenced by combined cataract surgery with high frequency deep sclerotomy (HFDS) and whether intraocular pressure (IOP) can be significantly reduced by HFDS. Methods: In our study 10 patients were included, in whom 24 h IOP monitoring was installed before and after HFDS/cataract surgery using a Triggerfish. HFDS is a minimally invasive glaucoma surgery (MIGS). Results: After performed HFDS combined with cataract surgery, the IOP was reduced from 27.7 ± 2.11 mmHg to 14.4 ± 2.59 mmHg, which is highly significant (p < 0.001). The contact lens sensor (CLS) cosinor analysis pre- and postoperatively showed that the circadian rhythm is not influenced by the surgery, i.e., the circadian IOP rhythm did not show significant differences before and after surgery. Conclusions: HFDS combined with cataract surgery is a potent surgical method that can significantly reduce the IOP. However, the circadian rhythm cannot be changed by the surgery. The acrophase remained during the night in all patients.

Physiological Approach

Cataract surgery decreases significantly and with maintained effect intraocular pressure (IOP) in both normal eyes as in eyes with glaucoma. In patients with cataracts and glaucoma, it can be performed, isolated or in combination with other techniques, such as the following: minimally invasive glaucoma surgery (MIGS) in patients with mild/moderate glaucoma that do not require a high tensional decrease; and conventional glaucoma surgery techniques in patients with advanced glaucoma. Although lower than with conventional techniques, MIGS trabecular surgery has a good IOP lowering effect and provides some of the following advantages: a more physiological approach; little traumatic; without bleb; and it does not limit other techniques in the future. Different techniques that combinated or not with cataract surgery facilitate the exit of aqueous humor through the trabecular meshwork (TM) have been described. Our aim in this chapter is to review the newest of them, such as the following: iStent; ELT (Excimer Laser Trabeculostomy); kahook; ABiC; and OMNI.

Harmonic Regression

Purpose: Cataract surgeries have been shown to reduce intraocular pressure. We used a Sensimed Triggerfish® contact lens sensor to compare intraocular pressure levels and their fluctuation between before and after cataract surgeries in patients with normal-tension glaucoma. Methods: This was a prospective open-label study. Thirteen patients with normal-tension glaucoma were included. All patients underwent a 1-month washout and discontinued glaucoma medications during this study. In each eye, intraocular pressure fluctuations over 24 h were measured with the contact lens sensor before and at 3 months after the cataract surgery. We compared intraocular pressure levels and their fluctuation between before and after cataract surgeries. We used two approaches to evaluate the amplitude of intraocular pressure fluctuations: dual-harmonic regression analysis, and measurement of the difference between the maximum and the minimum value. Results: The mean pre-operative intraocular pressure was 14.7 ± 2.2 mm Hg and mean post-operative intraocular pressure was 11.4 ± 2.2 mm Hg. Cataract surgery significantly decreased intraocular pressure (p = 0.0005). In both methods, the post-operative fluctuations in intraocular pressure over 24 h were significantly smaller than their pre-operative counterparts (dual-harmonic regression analysis: p = 0.0171; difference between the maximum and the minimum: p = 0.0398). Conclusion: Cataract surgery decreased both intraocular pressure values and intraocular pressure fluctuations in normal-tension glaucoma patients.
