## TL;DR

Using 3D visualization during cataract surgery helps reduce dry eye symptoms in patients compared to traditional methods.

## Contribution

This study shows that 3D visualization improves tear film stability and reduces dry eye symptoms after cataract surgery.

## Key findings

- The 3D group had significantly lower intraoperative light intensity than the conventional group.
- The 3D group showed better tear film stability and less eye redness at 1 week and 1 month post-surgery.
- Changes in tear breakup time correlated negatively with intraoperative light intensity.

## Abstract

To investigate the effects of the three-dimension visualization system on dry eye in patients after cataract phacoemulsification.

Seventy-one patients (104 eyes) were enrolled in this study and assigned to the conventional microscopic group (CM group) or three-dimension group (3D group). Ocular Surface Disease Index, The Schirmer I test (SIt), lipid layer thickness (LLT), noninvasive tear breakup time (NIBUT) and other factors associated with dry eye were recorded before and 1 week and 1 month after surgery. The operation time and intraoperative light intensity (ILI) were also recorded.

The ILI in the 3D group was significantly lower than that in the CM group (33% vs. 60%, p < 0.01). There was an interaction (group and time) effect for first NIBUT (NIBUT-F), average NIBUT (NIBUT-Ave), tear meniscus height (TMH) and the score of eye redness (Pinteraction < 0.05). The main effects of group on SIt, LLT, NIBUT-F, NIBUT-Ave and the score of eye redness were significant (Pgroup < 0.05). In the CM group, SIt, LLT, NIBUT-F, NIBUT-Ave, TMH were lower than those of the 3D group, the score of eye redness was higher than that of the 3D group at 1 week and 1 month after surgery (all p < 0.05). The changes in NIBUT-F and NIBUT-Ave between before surgery and 1 week after surgery showed negative correlations with ILI (p < 0.01).

Compared with microscopic surgery, the 3D visualization system can provide better tear film stability for patients after cataract surgery.
