Icl crystal-anterior chamber depth
The cavity between the posterior cornea, iris and lens in the eyeball is called anterior chamber.
The normal range of anterior chamber axial depth in China is 2.73-2.97mm, which is larger in men than in women and becomes shallower with age.
Why does ICL lens surgery require anterior chamber depth?
Because ICL lens surgery is an intraocular surgery, intraocular lens needs to be implanted in the eye to correct myopia and improve vision. Because it needs to be implanted in the eye, there needs to be a certain space in the eye to accommodate it.
(1) If the anterior chamber is too crowded, implantation of ICL lens may cause glaucoma attack.
(2) Narrow anterior chamber will increase the probability of contact between the implanted lens and its own lens, leading to premature cataract;
(3) If the anterior chamber is too shallow, the implanted ICL lens will affect corneal cells and lead to the decline of endothelial cells. If endothelial cells continue to decline, it will cause a certain degree of corneal decompensation and edema, which is irreversible and even needs corneal transplantation to improve.
Therefore, if the depth of anterior chamber is too shallow, less than 2.8mm, ICL surgery should be carefully considered and generally not recommended. For experienced experts, the condition of anterior chamber is slightly worse, so the possibility of operation can be evaluated. However, if it is less than 2.7mm, PRL suspension mirror surgery is recommended.
Three cases of icl crystal failure
With the technical innovation of ICL, there are fewer and fewer complications in surgery, and patients' satisfaction is getting higher and higher. However, some patients still report poor surgical results. What is the specific reason? Let's analyze it.
1, the crystallinity is not suitable.
The hardware conditions of ICL crystal surgery are not complicated, that is, the requirements for equipment are not high. Unlike full femtosecond, Zeiss equipment is necessary. ICL relies more on careful preoperative evaluation and examination, such as accurate optometry, to provide accurate support for surgery.
2. Cataract occurred after operation.
There is a risk of cataract after ICL lens surgery, which means that the lens is cloudy. Its high risk factors include:
(1) Age > 40 years old
(2) Arch height < 200μ m,
(3) High myopia (greater than 1500 degrees)
(4)V4 crystal (old model, non-porous crystal is used, in this case, V4C crystal can be used instead)
3, crystal rotation
In some patients, the arch height of ICL crystal rotation decreased due to trauma, and the arch height can be restored by adjusting the body position.
Conclusion: ICL lens implantation itself is safe and mature, and the individual situation is different, so it needs to be evaluated in combination with the patient's eye condition, and the choice of the operator is also very important.
