recognize astigmatism
The horizon of astigmatism, whether looking close or far away, is always accompanied by fuzzy ghosting, and the line clarity is inconsistent
In layman's terms, after the light enters the eyeball, it cannot be accurately focused on the retina, and the light appears to be emission, so the object becomes blurred
Astigmatism self-test map
The picture above is an astigmatism self-test table, remove the glasses, gently cover one eye, look at the center of the picture with one eye, if the thickness of each line is uniform, it means that there is no astigmatism, if you find that there are individual lines black and clear, indicating that there is a possibility
But, did you know that astigmatism is also different?
The astigmatism of the subjective refraction usually consists mainly of corneal astigmatism and intraocular astigmatism
Corneal astigmatism & intraocular astigmatism
Corneal astigmatism is mainly due to the irregular shape of the cornea, that is, the cornea is not "round" enough, the surface is not spherical, but like a rugby, it will cause different refractive forces in different directions to form corneal astigmatism
Intraocular astigmatism is astigmatism caused by intraocular factors other than the cornea
What are the effects of different astigmatism on choosing a myopia surgical approach?
Whether laser surgery (full femtoseconds, half femtoseconds, full lasers, excimers) or ICL lens implantation can correct a certain range of astigmatism, what is the difference between choosing which surgical method?
According to past cases, some patients may find that their vision is not as good as imagined after surgery, even one or two lines lower than the estimated postoperative vision, but some people may have postoperative vision that exceeds expectations
For these corneal astigmatism is relatively small, intraocular astigmatism is relatively large patients, we choose to do laser surgery when there will be some risks, we all know that laser surgery is through laser cutting on the cornea to correct myopia and astigmatism, but in fact, there may be no astigmatism on the cornea, we have to play a man-made astigmatism on the cornea, and then by it to synthesize the astigmatism in the eye, but with the growth of age, the crystal slowly hardens, the adjustment force declines, so that the crystal astigmatism may be small, this time, The astigmatism of the cornea is actually manifested, so that with age, the vision will become worse and worse
Moreover, in the future, after the occurrence of cataracts when you are old, you will encounter the problem of whether the implanted intraocular lens and the cornea after cutting can match, and you must find ways to eliminate the astigmatism of the cornea, which may affect the visual effect
For such patients, it is more suitable for ICL crystal implantation, because ICL surgery itself does not cut the cornea, does not affect corneal astigmatism, but is corrected by ICL crystals with astigmatism, in addition, it will not have an impact on
For patients whose corneal astigmatism is relatively large and because of the synthesis of intraocular astigmatism, ICL surgery or laser surgery can be selected
Pinnacle Ophthalmology Dual Navigation ICL Crystal Implantation
Four core strengths
Dual navigation escort crystal accurate worry-free
Zhengzhou Jianfeng Ophthalmology Innovation adopts the German ZEISS high-end surgical navigation system to escort the whole process of ICL crystal implantation surgery, which can not only accurately analyze the astigmatism axis to 1 degree, but more importantly, the intraoperative judgment arch is high, which greatly improves the accuracy of ICL surgery and reduces the risk of
Callisto eye positioning navigation:
Non-marking marking, real-time tracking and positioning of incision and astigmatism axis, more accurate surgery, and clearer vision after surgery;
Rescan700 intraoperative OCT navigation:
Intraoperative real-time observation of crystal position, so that surgical experts can make reliable predictions of postoperative arch height, timely adjustment of the crystal during surgery, to provide postoperative peace of mind;
Adhesive-free underwater implantation
The whole operation adopts underwater implantation technology, and no viscoelastic agent is used, so as to avoid the problem of postoperative intraocular pressure increase caused by the residue of the viscoelastic agent and reduce the risk of
Auxtigamtism
Self-developed software astigmatism assists positioning
Using the Auxtigamtism Optical Auxiliary Positioning App, which was personally developed by President Liu Baosong, the auxiliary intraoperative navigation equipment performs double accurate calibration, which achieves more accurate astigmatism correction
The dean personally consulted the operation and the strength of the guardian was more at ease
ICL Crystal Implantation Surgery was officially launched in China in 2006, and in the same year, President Liu Baosong obtained the ICL official surgical expert certification, helping tens of thousands of myopic patients successfully regain high-definition vision
